The case, in 18kt rose gold, or in platinum, measures 42mm x 7.45mm. It has double sapphire crystals and it is water resistant to 30 meters. Finely fluted caseband. Welded lugs with screw-secured bars.
Movement is the Swiss automatic Breguet in-house caliber 581 with 33 jewels, 28,800 vph and a power reserve of 80 hours. Extra-thin (3 mm) rhodium-plated movement. Barrel mounted on roller bearings. Inverted lateral lever escapement with silicon horns. Silicon balance spring. Tourbillon with titanium carriage. Small seconds on the tourbillon axis. The bridges, barrel and rotor are hand-engraved. Crafted in platinum for greater inertia, the latter rotates on the periphery of the caliber.
Dial in Grand Feu enamel, signed Breguet. Chapter ring with Breguet Arabic numerals. Breguet open-tipped hands in blued steel. Breguet has opted for a graphic hand-bevelled tourbillon bar, topped by a spinel. The chapter is off-centred at 11 o'clock and thus directly facing the tourbillon at 5 o'clock.
It comes on a blue or mahogany brown alligator leather strap with an 18kt rose or white gold gold folding clasp.
Thanks.
