Insider: Breguet Marine Royale ref. 5847. A Diver's Watch with Alarm Mechanism.

The Breguet Marine Royale ref. 5847BR/Z2/5ZV is a massive timepiece with an 18K rose gold case featuring an automatic movement with an alarm mechanism and a sporty rubber strap. The case measuring 45mm in diameter and 17.45mm in thickness is very solid, masculine and crafted like a tank. The caseband is engraved with the traditional Breguet fluting and the watch is fitted with a very solid and thick turning bezel with luminous mark at 12 and security wave shaped ratchet at 3 o'clock right between the winding crown located at 2 and the alarm setting crown —fitted with a black rubber ring— at 4 o'clock. The alarm on/off push-piece is located at 8 o'clock in the shape of a wave, with rubber casing and fluting.

The dial appears to look like a ruthenium dial and it features a beautifully done rose engine wave 'guilloché' pattern at the center and the outer rim, applied Roman numerals chapter ring in rose gold, luminous dots minute chapter on the outer rim of the dial, blue dot alarm setting chapter ring on center of dial, blue arrow-head alarm hand,  alarm on/off indicator at 12 with a musical note in blue, blue and white alarm power reserve indicator at 10 and a date aperture at 6 o'clock with black calendar disc and white font. The dial is completed by the Breguet style hands with applied luminova. A downside of the dial is that the luminova is not very powerful.

This beautiful timepiece is powered by the automatic Breguet calibre 519 R that beats at a frequency of 28,800 vph with 36 jewels and that provides a power reserve of 45 hours when fully wound. This calibre is one of the most beautiful movements we've seen lately and it is fully visible via the display case back. Regardless of its display case back, this watch is waterproof rated to a depth of 300 meters. Additionally the finish of the case back is just spectacular and exceptionally executed. The third picture shows the alarm mechanism in action.

The Breguet Marine Royal ref. 5847 is fitted with a nice and thick rubber strap with pyramidal square pattern near the lugs and wave pattern on the inside with Marine Royal in blue —a very nice and unique touch. The strap comes fitted with a double-folding clasp with easy adjustment pin buckle in rose gold and with two rose gold fasteners shaped as waves. 

In summary, this is a fascinating sports watch that is very solid, large and comfortable on the wrist. The strap wears like a glove and the alarm complication is just fascinating. The watch wears way larger than its actual size on a 7-7.25" wrist and almost like a 50mm timepiece —nothing wrong as long as you like to wear big watches. This watch is also available in white gold, white gold with black dial and rose gold with rose gold dial.
