Breguet Marine Titanium — Sunburst Slate Dial Date | Ref. 5517TI/G2/9ZU

The Marine collection draws its authority from Breguet's appointment as official chronometer supplier to the French Navy in the early nineteenth century, when Abraham-Louis Breguet's marine timekeepers set the standard by which longitude at sea was measured. The 5517TI/G2/9ZU translates that naval heritage into a contemporary sports watch of notable efficiency: a 40 mm titanium case — chosen for its combination of structural rigidity and lightness on the wrist — houses calibre 777A, a self-winding movement delivering approximately 55 hours of power reserve within an 11.5 mm profile.

The sunburst slate grey dial is the 5517's defining characteristic. Its radial brushing catches ambient light with a depth that no flat colour can replicate, shifting from near-charcoal at the centre to a cooler pewter tone toward the chapter ring. Date indication at three o'clock provides the sole complication, keeping the visual field clean and the movement's proportions unencumbered. A sapphire crystal caseback reveals the rotor architecture without compromising the watch's water resistance to 100 metres — a specification that situates the 5517 firmly as a serious nautical instrument rather than a decorative homage.

The brown leather strap softens the case's technical character, bridging the Marine's nautical functionality with the formal versatility demanded by collectors who wear the same watch from morning meetings to weekend voyages. Titanium's inherent hypoallergenic properties and resistance to corrosion make the 5517 an especially appropriate choice for a Marine-collection piece intended for sustained contact with salt air and sea spray. At $14,640, this is Breguet's most accessible entry into a collection with two hundred years of maritime credibility behind it.
