About the Omega Trésor

The 1949 Trésor was a gold dress watch on the caliber 30 T2, and the 2014 revival kept the shape and put a new movement behind it: the 8511, the first hand-wound co-axial caliber built to resist 15,000 gauss, with a 60-hour reserve. The 2018 relaunch added the ladies' Trésor at 36 mm and 39 mm, quartz, with a row of diamonds set into each side of the case, and the Mini Trésor of 2021 at 26 mm. The men's line moved to the Master Chronometer hand-wound 8910 and its gold-rotor variants, with a small-seconds and power-reserve model.

Quartz is the majority here: the 4061 powers 61 references, the ladies' 36 mm and 39 mm and the Mini. Hand-wound movements account for 36, the 8511 in 19 and the 8910 family in 15, and 3 references are automatic. The collection's median case thickness is 8.85 mm.

Sizes divide by model: 40 mm for 36 references, 26 mm for 28, 36 mm for 26 and 39 mm for 7. Steel is the material of 48 cases, and Omega's own gold alloys make up most of the rest: Moonshine gold in 21, Sedna gold in 13, with yellow gold, white gold and a single Canopus gold case behind them. White dials account for 39 references, silver for 18 and blue for 13. Water resistance is 30 m throughout. 6 references are limited editions.

The De Ville is the collection the Trésor grew out of, and the Constellation the dress alternative with an integrated bracelet; the glossary covers the Master Chronometer standard the hand-wound models meet.
