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.
