With the Breguet Marine Royale 5847 — part of its boutique-only Les Exclusifs de Breguet collection — the Swiss watch brand founded by watchmaking pioneer Abraham-Louis Breguet has created not only a distinctive sport-luxury timepiece with a mechanical alarm, but one that could actually prove useful for divers. The alarm function incorporated into this watch’s automatic movement is designed to work underwater, to a depth of 300 meters, meaning it can be set to remind a diver when his air is running low and it’s time to resurface. Despite this practical “tool watch” complication, the Marine Royale 5847 is still seriously elegant and emphatically Breguet: the chocolate-toned dial (which matches the textured rubber strap) has a hand-engraved rose engine pattern, and the case, along with its unidirectional rotating bezel, is made of 18k rose gold. The watch has a date window at 6 o’clock, a power-reserve indicator at 10 o’clock, and an “alarm on” indicator at 12 o’clock. The Breguet Marine Royale 5847 retails for $46,300.
