Finally, this week at Baselworld 2015 we were able to work on our hands-on review of the new Arnold & Son Constant Force Tourbillon unveiled pre-Baselworld a few weeks ago. This time, Arnold & Son pushes precision chronometry ever further with the Constant Force Tourbillon, featuring a patented constant force device with 60-second tourbillon and true beat seconds. The symmetrical movement architecture of the Constant Force Tourbillon movement pays tribute to Arnold & Sons' historic marine chronometers. At the top, two visible mainspring barrels and the constant force device provide optimal power to the tourbillon at the bottom of the dial. The Constant Force Tourbillon has two symmetrical barrels in series, visible dial side on its anthracite open dial at 10:30 and 1:30, tourbillon at 4:30 and constant force mechanism with built-in dead beat seconds at 7:30. This elegant complication is fitted with a massive 46 mm 18K red gold case —that surprisingly doesn't wear too big, perhaps because of its double-step bezel—, satin brushed finished lug sides, equipped with a beautiful light brown alligator strap with double folding buckle and a display case back.

Pre-Baselworld 2015: Arnold & Son Unveils the Golden Wheel. World's First Wandering Hours and True Beat Seconds Watch.
With a rich British watchmaking heritage that dates back to the 18th century, Arnold & Son masterfully reinterprets history with a visionary eye to the future. Underscoring its watchmaking prowess, Arnold & Son regularly unveils complicated watches with a unique twist. The patented Golden Wheel deftly reflects the brand’s ingenuity and commitment to Haute Horlogerie. The Golden Wheel timepiece is a unique three-dimensional interpretation of the ancient wandering hours complication that has roots in table clocks of the mid-17th century. In fact, the first implementation of the wandering hours complication in pocket watches was most likely made in England at the beginning the 18th century. Thus, it is a fitting complication for the Arnold & Son watchmakers —inspired by British watchmaking heritage— to reinvent anew, perpetuating the long tradition of wandering hour watches.
News: Presenting the Arnold & Son HMS Beagle Set. Limited Edition of Eight Sets of Three timepieces each.
Continuing with their limited edition product strategy, this time Arnold & Son presents a trio of timepieces commemorating Charles Darwin’s voyage of discovery. The HMS Beagle Set is composed of eight limited edition sets of three timepieces each, honoring the HMS Beagle ship that was used by Charles Darwin to set foot at the Galapagos Island. While the HMS Beagle undertook three survey voyages in all, it was the second one, with naturalist Charles Darwin on board, that guaranteed its place in history. With this set of three watches, each featuring an exquisite hand-painted miniature of HMS Beagle, Arnold & Son pays tribute to one of the most celebrated ships in the history of exploration.
Introducing: Arnold & Son Royal TES Tourbillon. Hands-on Live Pictures of a Exceptional and Very Exclusive Timepiece.
True to English watchmaking heritage, Arnold & Son unveils the TES Tourbillon, with the hand-finished A&S8100 calibre with sapphire barrel bridge. This defining timepiece is part of the Royal Collection which combines classic styling with leading-edge technology. The tourbillon movement, one of the most elegant complications in the world of horology, has played a crucial role in Arnold & Son’s history. An exceptional watchmaker, John Arnold was an active participant in one of the most extraordinary partnerships in the world of innovative horology. Indeed, both he and Abraham Louis Breguet worked closely, sharing both their knowledge and passion. Evidence of their partnership is Abraham Louis Breguet’s first ever tourbillon mounted in John Arnold’s No. 11 movement, a watch that can be found today in London’s British Museum.
Baselworld 2014: Arnold & Son CTB. A True Beat Seconds Chronograph. Live Pictures and Pricing.
The new Arnold & Son CTB —Chronograph True Beat— ref. 1CHAS.S02A.C121SCTB features an in-house mechanical movement with a true beat seconds chronograph. Fitted with a highly polished generous case measuring 44 mm in diameter in stainless steel or 18K rose gold, the magnificent Arnold & Son CTB represents the brand's second chronograph where a central true beat seconds hand and a central chronograph seconds hand had been incorporated on the same axis but with different jumping intervals —a huge technical challenge to have both functions operating from the central pinion.
This new watch featuring a subsidiary hour/minutes dial at 12 and a subsidiary running seconds register at 6 o'clock is fitted with a true beat seconds 60-minute chronograph a.k.a dead beat seconds which is a precision function wherein the seconds beat incrementally as opposed to sweeping along the dial, thus allowing for more accurate reading. To accomplish this function Arnold & Son has taken the idea to new heights by incorporating the true beat seconds on the same axis as the chronograph seconds hand. The result, when the continually running chronograph hand is started, is visually amazing. It gives the impression that it can catch up to the true beat seconds hand, but this never happens since the true beat seconds hand jumps away each second in a delightful and entrancing game of cat and mouse. The stainless steel timepiece is offered with a light-grey and silvery opaline dial while the 18K rose gold model features a more off-white dial. The dial has a complex multi-level structure with at least three different finishes that offer breathtaking depth and dimension.
The A&S7103 automatic calibre is a proprietary movement with column-wheel operated chronograph and is fully visible via the display case back. The 31-jewel movement beats at 28,800 vph and offers more than 50 hours of power reserve when fully wound. Each movement is NAC grey treated and meticulously completed in Haute Horlogerie finishing with hand-chamfered bridges with polished edges, fine circular graining and Côtes de Genève rayonnantes, brushed and skeletonized rotor, and screws with bevelled and mirror-polished heads.
The movement is configured to give optimum balance and beauty to the dial, with off-centered hour and minutes at 12 o'clock, big central true beat seconds and central chronographs seconds and 60-minutes chronograph indicator at 6 o'clock. While the winding crown and pushers have been meticulously finished and designed to resemble antique marine chronometers in a very elegant way.
This line is inspired by the timepieces produced during the second part of John Arnold's life when he and his son, John Roger, dedicated themselves to the quest for absolute precision establishing themselves as official suppliers to the Royal Navy.
On the wrist, just as expected, the watch wears true to its size and very elegantly. If you like to play with your chrono while listening to a boring conference call with your partners down in Tokyo, this is a perfect timepiece to help you kill time and keep time with precision during your Six Sigma training.

Baselworld 2014: Arnold & Son Royal TEC1. Live Pictures and Pricing.
In honor of Arnold & Son’s 250th Anniversary, the manufacture unveils the Technically Advanced Tourbillon Chronograph: the Royal TEC1. Globally renowned for its rich British heritage and inimitable excellence in watchmaking, Arnold & Son unveils an inventive new timepiece that underscores its commitment to Haute Horlogerie. The new TEC1 wristwatch is at once both alluring and intriguing. It masterfully integrates three complexities never before combined by the brand in such an elegant rendition. A tourbillon, a column wheel 60-minute chronograph and an automatic winding system deftly blend in a superb avant-garde yet classic new timepiece.
The TEC1, the brand’s third tourbillon, joins the sophisticated Royal Collection, which is inspired by the timepieces created in the early part of John Arnold’s life for King George II and members of the royal court. This sophisticated new Royal TEC1 is a worthy example of Arnold & Son’s innovative spirit, technical prowess and artistic achievement. The A&S8305 calibre is an exclusive mechanical self-winding movement that offers hours, minutes, tourbillon and 60-minute chronograph.
The challenge for Arnold & Son’s Research and Development team in creating this timepiece was the integration of a high-frequency tourbillon, a chronograph and an automatic winding system in a way that is elegant and technically advanced. As such, the traditional layout of a movement with these functions has been totally discarded and all-new engineering was required for the new calibre. The tourbillon escapement majestically occupies the entire top portion of the dial from 10 o’clock to 2 o’clock with an oversized aperture that offers an incredible three-dimensional effect as the tourbillon cage rotates.
With a sapphire crystal and display case back, the aperture allows for a view that is totally unencumbered and breathtaking. The Royal TEC1 is the brand’s first high-frequency tourbillon, with 28,800 vibrations per hour and with a generous power reserve of 55 hours. The lower portion of the dial features the chronograph function, with the 60-minute register strategically located at 6 o’clock for harmonious balance. The chronograph seconds are registered via a central seconds hand. Making the watch even more technologically savvy is the fact that it is built with a column wheel chronograph —whose large column wheel is visible via the transparent sapphire case back. Implementing an integrated automatic winding system that winds in both directions further highlights the haute horological finesse of the brand.
In typical Arnold & Son tradition, the calibre A&S8305 with 255 parts and 30 jewels is meticulously finished. Each palladium treated movement boasts manually chamfered bridges with polished edges, fine circular graining and Côtes de Genève rayonnantes. The chronograph levers are satin-finished with hand-chamfered, polished edges and all screws are blued with bevelled and mirror polished heads. The highlight of each watch is a 22-carat red gold skeletonized rotor that is breathtakingly beautiful thanks to hand-engraved craftsmanship, its brushed surfaces and chamfered polished edges.
Three different references are available. The Limited Edition 250th anniversary piece is crafted in 18K red gold 45 mm case and features a stunning blue lacquered guilloché dial. The 22K red gold rotor is hand-engraved with the inscription: 250th Anniversary. Two additional non-limited renditions are also being offered: the alluring 18K red gold model with anthracite dial featured here and a palladium cased version with a silvery white and silver dial that appears on the wrist shot at the bottom of this post.

Baselworld 2014: Arnold & Son DSTB Dial Side True Beat. Live Pictures and Pricing.
Demonstrating its rich British history and quality Swiss craftsmanship, Arnold & Son unveils the limited edition DSTB —Dial Side True Beat. A tribute to the brand’s 250th anniversary, the DSTB is a testament to its heritage, vision and Haute Horlogerie ingenuity. The true beat seconds is a traditional complication of Arnold & Son, and this watch pays tribute to the watches produced by John Arnold during the second half of his career, when he and his son were the first to develop marine chronometers. Upholding that legacy, Arnold & Son’s master watchmakers thrive on creating complicated movements for exquisite timepieces. Such is the case with the DSTB watch, a truly innovative technical and architectural achievement. The newly developed automatic movement showcases the true beat seconds' mechanism entirely on the dial side. Not just the hands, but also the lever, wheels and three rose-gold treated true beat seconds bridges are located in all their beauty on the dial side. Making the watch even more alluring is the fact that the true beat seconds lever is shaped like an anchor paying homage to Arnold’s maritime achievements.
The true beat seconds are superbly indicated via a large sapphire dial that occupies the top left portion of the dial at 11 o’clock. At the 4 o’clock position, a white lacquered domed subdial indicates the hours and the minutes via blued hands. These generously proportioned, overlapping indications translate into a stunning three-dimensional dial. This restructuring of the intricate mechanism yields a concept not achieved in the watch industry heretofore.
The self-winding calibre A&S6003 has 229 components. In true Arnold & Son style, the movement features Haute Horlogerie finishing with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève rayonnantes. The visible dial plate is NAC grey treated with large circular finishing, and blued screws with bevelled and mirror-polished heads.
The magnificent timepiece is housed inside a 43.5 mm 18-carat red gold case with anti-reflective sapphire crystal and caseback for viewing the superbly finished movement, complete with skeletonised oscillating weight. The 250th anniversary edition of the DSTB will be limited to just 50 timepieces underscoring the brand’s commitment to exclusivity and excellence.

News: Pre-Baselworld 2014 Arnold & Son Presents the DTE: Double Tourbillon Escapement Dual Time Watch. Another Masterpiece of Horology.
John Arnold was born in Cornwall in 1736. His father was a watchmaker and his uncle a gunsmith, which probably explains his early interest in precision engineering and metalwork. A talented craftsman and scholar, he left England for the Netherlands at the age of 19 after completing his apprenticeship to hone his watchmaking skills. He returned two years later speaking excellent German, which stood him in good stead later at the court of George III, and had established himself as a watchmaker of repute in London's Strand by his mid-twenties. After Arnold presented the smallest repeating watch ever made to King George III and to the court, he rapidly acquired a wealthy clientele. He was one of the most inventive watchmakers of his day and held patents for a detent escapement, bimetallic balance and helical balance spring. Arnold's "No. 36" was the first timepiece to be called a chronometer, a term reserved for unusually precise watches to this day. Arnold also played a central role in the events of his day. Along with other watchmakers, he addressed the problem of determining longitude, and won several grants and awards offered by the British Parliament. He enjoyed such respect in his profession that he became a close friend of Abraham-Louis Breguet. The timepieces of Arnold and his son accompanied famous explorers on their voyages of discovery, helped the East India Company establish its empire and how Napoleon Bonaparte himself presented an Arnold clock to the Observatory of Milan in 1802.

250 years later, Arnold & Son celebrates its 250th anniversary with another masterpiece of horology in a limited edition of only 28 pieces, the DTE: Double Tourbillon Escapement Dual Time watch. A generous 43.5 mm watch 18K red gold with two white dials —one with Roman numerals and the other with Arabic numerals— accentuated with blued hour and minute hands. The DTE is a masterpiece of symmetry, balance and three-dimensional beauty combined with technical foresight and ultimate performance precision.
The double barrels of the watch offer a superb 90 hours of power reserve. In typical Arnold & Son style, the watch is incredibly detailed and features superlative Haute Horlogerie finishing. The dial side of the timepiece offers symmetry and depth. It features two white lacquered domed dials – one each at 12 o’clock and 6 o’clock – for the dual time displays. The two tourbillon escapements are harmoniously balanced at 3 o’clock and 9 o’clock and seem to float over the dial thanks to their alluring raised 18K red gold bridges. The backdrop for these double lacquered dials and double tourbillon escapements is a magnificently decorated vertical Côtes de Genève stripes plate.
The two crowns – one each for setting the local and the home time – are located at 2 o’clock and 8 o’clock, and the two mainsprings are wound using the crown at 2 o’clock. In addition to the double tourbillon escapement and the dual dial/dual time indication, the watch is incredibly efficient in that it not only offers local time in hours and minutes, but also offers hours and minutes of a second time zone to be set separately —thereby enabling the wearer to have precise time in zones that differ from Greenwich Mean Time by quarter-hour or half-hour increments. Each time zone display has its own gear train and its own tourbillon escapement.
The watch, powered by the all-new mechanical hand-wound calibre A&S8513 —visible via the display case back—, brings the centuries-old tradition of double movements back to life in 21st century style. The watch is fitted with an very elegant hand-stitched brown or black alligator strap.

News: Arnold & Son Presents the TB Victory Special Limited Edition. A Tribute to Britain's National Museum of the Royal Navy in a Unique Piece.
A Tribute to the National Museum of the Royal Navy: Arnold & Son Announces Special Limited Edition of the TB Victory Britain’s National Museum of the Royal Navy comprises five museums that document the part played by the Royal Navy in the shaping of the nation and of the modern world. One of those Museums is HMS Victory, the world's most famous warship, which had her finest hour as Lord Nelson's flagship at the Battle of Trafalgar in 1805. With this special, one-piece edition of the TB Victory, Arnold & Son pays a special tribute to one of the nation’s most valued institutions. Some 250 years ago, John Arnold and his son, John Roger, played a central role in developing the chronometers that enabled 18th-century navigators to determine longitude at sea and helped establish the Royal Navy as the dominant force on the world’s oceans. Today, the company looks back with pride on that contribution. As Philippe Boven of Arnold & Son explains: “We are keenly aware of the close links between our company and the Royal Navy, and are presenting this special edition of the TB Victory to the National Museum as an expression of our respect and admiration for the Museum which keeps that unique heritage alive.” His sentiments are mirrored by those of Dr. Dominic Tweddle, Director-General of the National Museum of the Royal Navy: “I am delighted and honored to accept this unique timepiece from Arnold & Son on behalf of the Museum. It is an acknowledgement, exquisitely executed, of the significant role that HMS Victory has played in a long and glorious history.”
The TB Victory timepiece has a distinctive off-centered subdial for the time of day, one of the unmistakable design cues of the Instrument Collection. Central to the cream colored dial is the timepiece’s complication: a central true beat —TB— seconds. A rarely found complication these days, the true beat seconds —or dead beat seconds— stands for superlative accuracy and was an invaluable instrument for marine navigators. The combination of a central true beat seconds with an automatic winding system calls for enormous technical expertise. This is made possible by an internationally patented system and calls for parts accurate to a micron, or one-thousandth of a millimeter. The key components are produced using state-of-the-art LIGA —lithography, electroplating and molding— manufacturing technology. The TB Victory is powered by the A&S6103 calibre, the first automatic movement with an integrated true beat system to be developed, designed and manufactured entirely at Arnold & Son’s workshops in La Chaux-de-Fonds. The exquisite Haute Horlogerie finishing includes manually chamfered bridges and polished edges, fine circular graining and 'Côtes de Genève rayonnantes', a brushed and skeletonised rotor, and blued screws. This unique edition of the TB Victory will be restricted to the single timepiece presented to the National Museum of the Royal Navy.

News: Arnold & Son Unveils the Time Pyramid in Stainless Steel. A Fascinating Timepiece and a Real Treat for the Eyes.
Arnold & Son unveils a new reference of its iconic Time Pyramid featuring the hand finished A&S1615 calibre treated in NAC grey, housed in a stainless steel case. The A&S1615 movement with unique skeletonized pyramid-shaped architecture, was conceived, designed and developed in-house. The movement A&S1615 seemingly floats between two sapphire crystals, the Time Pyramid is a masterful rendition of technical prowess and unparalleled elegance. This superbly engineered wristwatch is part of the brand’s Instrument Collection that combines instrument precision with classical styling.
Inspired by the regulators created by John and Roger Arnold over two hundred years ago, and by antique British skeleton clocks, the new Arnold & Son Time Pyramid offers a highly cohesive and seductive blend of watchmaking feats that includes regulator, skeleton, vertical linear movement, pyramid-placement of components and multi-dimensional depth.
The skeletonized caliber A&S 1615 follows the original regulators from the brand with its component positioning and detailed 3D visual appeal. Movement parts and watch indications are built on three levels, with the subsidiary seconds dial on the bottom, the hour indications on a sapphire crystal dial in the middle level, and a silver top ring for the minutes indication. While the movement is extremely thin-at just 4.4 mm —the multiple levels bring amazing depth and detail to the watch. To further enhance the balance and symmetry of the Time Pyramid, the crown —with Arnold & Son’s engraved logo— is artfully positioned at six o’clock. The gear train runs vertically in a linear format connecting the two barrels at six o’clock to the balance wheel at twelve o’clock, and endowing the movement with its pyramid structure.The bridges are designed so that all of the wheels, the two main spring barrels, the escapement and balance wheel are all magnificently visible from the dial side.
Additionally, the movement is fitted with two power reserve indicators –one each on either side of the linear gear train –to display the energy level for each barrel separately. The power reserve hands indicate the reserve level via graduated dots —that are printed under the top sapphire crystal— in an arc format, and demonstrate how one barrel transfers energy to the second one when needed. Essentially, as the first barrel winds the second one, the power reserve indicator of the first barrel goes down, while the second one goes up –making for an accurate and intriguing readout. The two mainspring barrels supply the hand-wound caliber with an amazing 90 hours of power reserve, and provide a more constant force to the wheel train. As with every esteemed Arnold & Son watch, the movement of the Time Pyramid is magnificently hand decorated with manually chamfered brides and high-polished edges, Côtes de Genève, circular satin- finished wheels and blued screws, all yielding a striking masterpiece of decorative craftsmanship and brilliant execution.
Each Time Pyramid wristwatch measures 44.6 mm in diameter in its classically elegant stainless steel case. Viewed from the side, the housing is stepped and tapers from top to bottom, the widest section accommodating the extra-large glass with the lower part narrowing to fit snugly on the wrist. Each is finished with an exquisite hand-stitched alligator strap.
