Breguet Marine Royale 5847 comes with an alarm device that can only delight both amateur divers and aficionados of exceptional complications. Underwater tests confirm that sound travels better through water than through air. Sound waves require material support and their speed increases with the density of the environment. Sound travels about four times faster under than above water. Furthermore, as the underwater milieu is generally far less noisy than the aerial one, the alarm’s sound is perceived with greater clarity underwater.
The alarm setting crown and on-off pushpiece, in gold, are sheathed in rubber for easier handling, adding a further touch of sporty elegance. The Breguet watch naturally possesses the usual diver’s-watch features, not least a one-way rotating bezel inscribed with a graduated 20-minute sector. The bezel’s unidirectional rotation is secured by a blocking pawl, visible and located between the two winding crowns on the case flank. Shaped like a wave, it recalls the watch’s essential functions. To improve its legibility even in the murkiest waters, its minute markers and hand along with the hour hand are coated with white luminous superluminova while the hour and alarm markers glow blue. Represented by a blue triangular pointer at 10 o’clock, the power-reserve indicator is also luminous.
