ON A SLIM LEATHER STRAP WITH A STEEL BUCKLE, THE TRÉSOR IS A STUDY IN MODERN MINIMALISM—ON PAPER IT’S A MEDIUM-SIZED MODEL, BUT IT’S DRAWN SO THIN AND CLEAN THAT IT BEHAVES, VISUALLY AND PHYSICALLY, LIKE A MUCH SMALLER WATCH

OMEGA DE VILLE TRÉSOR 40MM
REF. 435.13.40.21.03.001
On paper, 40mm may look generous for a collection of“powerfully small”watches, but the De Ville Trésor line is a reminder that diameter is only one part of the equation. In stainless steel, the reference 435.13.40.21.03.001, with its rich blue dial, measures 40mm across and sits around 10.1mm tall on the wrist, yet the combination of an ultra-slim bezel, curved lugs, and minimalist dial design means it wears flatter and more discreetly than many 38mm sports watches. The case is polished, with a slightly domed sapphire crystal and a simple crown, giving the watch an almost vintage dress profile. Inside is the hand-wound calibre 8910, part of Omega's Master Chronometer family. It beats at 25,200 vph (3.5Hz) and offers a 72-hour power reserve from twin barrels, delivering both weekend-proof autonomy and a satisfyingly tactile winding experience.

The movement is certified by METAS as a Master Chronometer, meaning it has passed rigorous tests for precision, isochronism and resistance to magnetic fields greater than 15,000 gauss. It uses a Co-Axial
escapement, free-sprung balance and silicon balance spring, all visible through the sapphire caseback. The watch is rated to 30 metres of water resistance, which is more than sufficient for a dress watch. On a slim leather strap with a steel buckle, the Trésor is a study in modern minimalism – on paper it’s a medium-sized model, but it’s drawn so thin and clean that it behaves, visually and physically, like a much smaller watch.
