De Ville Trésor Tourbillon Sedna Gold / Blue

In Context

At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 45 hours of reserve carries it overnight, but not through a weekend in a drawer.

528.53.44.21.03.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a sedna gold case. Beyond the time it carries a tourbillon.

Self-winding movement with Co-Axial escapement. Blue PVD coated tourbillon base with sun-brushed finishing, hand polished bridges and mechanisms, Breguet balance-spring, 950 platinum oscillating weight. Titanium tourbillon cage rotates completely once every minute. Watchmaker’s initial on the back of tourbillon’s main plate. Officially certified chronometer.
