Breguet Marine Tourbillon Equation Marchante 5887

The Breguet Marine Tourbillon Equation Marchante 5887 (reference 5887PT/YS/PW0SL) is housed in a 43.9 mm round 950 platinum case with a sapphire caseback, water resistant to 100 metres. The blue dial is created using grand feu enamel miniature painting on a sapphire disc. It is powered by the self-winding Breguet calibre 581DPE, featuring a peripheral oscillating weight engraved with the "Royal Louis" vessel and offering 80 hours of power reserve. The movement combines a tourbillon with a running equation of time, a perpetual calendar, and an off-centred power-reserve display.
