Omega De Ville Hour Vision Annual Calendar, 41mm, Co-Axial Calibre 8601 Automatic Chronometer, 431.33.41.22.02.001

The OMEGA De Ville Hour Vision Annual Calendar Ref. 431.33.41.22.02.001 combines sophisticated dress-watch design with one of OMEGA's more technically interesting calendar movements. Its 41mm stainless steel case frames a two-zone silver dial, with the month and date displayed together at 3 o'clock and a black alligator leather strap completing the refined presentation.

The Hour Vision collection was originally introduced in 2007 and distinguished itself through an unusually architectural case construction designed to provide greater visibility of the movement. Sapphire elements complement the transparent caseback, allowing the finishing and mechanics of the movement to become an integral part of the watch's design. This reference is now discontinued.

At its heart is the OMEGA Co-Axial Calibre 8601, a self-winding chronometer movement developed specifically with an annual calendar complication. The mechanism automatically distinguishes between 30- and 31-day months, requiring manual correction only once each year at the end of February. The Calibre 8601 provides approximately 55 hours of power reserve and incorporates OMEGA's Co-Axial escapement and twin barrels.
