Steel on leather strap
435.13.40.21.02.001
Characterised by its thin and elegant case, the Trésor line was first launched by OMEGA in 1949 and housed the legendary 30mm calibre. More than half a century later, it continues to impress with one of today’s most advanced mechanical movements.
This model has a 40 mm stainless steel case, which is presented on a black leather strap. The domed opaline silvery dial includes a date window at 6 o'clock as well as hands and indexes in 18K white gold.
Inside, this De Ville Trésor is powered by the OMEGA Co-Axial Master Chronometer Calibre 8910 and is certified at the industry’s highest standard of precision, chronometric performance and magnetic resistance.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.

Transparent case back
A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.
