Here we have the 2010 model for Breguet’s Marine collection. This lovely timepiece features a 45mm 18-carat white gold case, automatic movement, alarm (marked by the blue triangular hand), date, luminous hands and a sapphire-crystal case-back. The bezel’s unidirectional rotation is secured by a blocking pawl, visible and located between the two winding crowns on the case flank.

To improve its legibility even in the murkiest waters, its minute markers and hand along with the hour hand are coated with white luminous super-luminova while the alarm markers glow blue. It should be noted that the Breguet Marine Royale features an alarm that can be operated underwater to a depth of 300 meters – and heard with excellent clarity. [via perpetuelle]
