Omega’s Caliber 8511 movement has a 60-hour power reserve due to its two barrels and it is also antimagnetic to 15,000 gauss. The technology Omega used for its Seamaster Aqua Terra > 15,000 gauss is now widely embedded in the company’s in-house movements (with the exception of chronograph movements).
With its 10.6-mm-thick case it is not the thinnest dress watch, but given the fact that it does have a date complication and an extra time zone function, I think that’s fine. The diameter of the De Ville Trésor Master Co-Axial case is 40 mm. The beautiful, silvery opaline dial with its “Clous de Paris” pattern is protected by a nicely domed sapphire crystal. The sapphire crystal has nonreflective coating on both sides.
At 6 o’clock, you will find the date aperture, where Omega placed it on its Omega Seamaster Calendar watches from the 1950s. Furthermore, you will find long, domed gold hour indices, including two each at 12, 3, 6 and 9 o’clock. The ones at 6 o’clock are slightly shorter, as they are interrupted by the date aperture. The dial is very clean: there is text mentioning the Master Co-Axial movement and the fact that it the watch is chronometer-rated, but that is it. The dial in a dress watch should be as clean as possible, in my opinion. Perhaps Omega could even have left out the Master Co-Axial text, but the does seem well-balanced this way.
My watchmaker – who has a weak spot for vintage Constellation watches – often complains to me that watch manufacturers don’t make dials like this anymore. I’m glad to report that Omega just did. The Omega De Ville Trésor Master Co-Axial comes in three different versions: white gold, yellow gold and Omega’s proprietary Sedna gold. Prices range from $13,800 to $15,000.
