De Ville X2 Big Date (7813.50.31)

What makes the Omega De Ville X2 Big Date special is its unusual square case, distinctive Art Deco dial and oversized date display. It combines vintage-inspired styling with Omega’s Co-Axial chronometer movement, making it a distinctive and less conventional choice for collectors.

The Omega De Ville X2 Big Date Ref. 7813.50.31 has a distinctive Art Deco design that gives it a strong personality. Its 35mm square stainless steel case features polished surfaces and elegant lines. The black dial creates a striking contrast with the applied Roman numeral hour markers, silver-tone hands and railway-style minute track. The oversized date display at 3 o’clock adds character and makes the watch easy to read. Omega protects the dial with a domed sapphire crystal that features an anti-reflective coating on the inside. The watch comes fitted with a black alligator leather strap and a stainless steel folding clasp, which complete its elegant appearance.

Inside the watch, Omega uses the automatic Co-Axial Calibre 2610. This movement features Omega’s Co-Axial escapement, a technology designed to reduce friction and improve long-term performance. It operates at 25,200 vibrations per hour and provides approximately 48 hours of power reserve. The movement also carries an official COSC chronometer certification, which confirms its accuracy through independent testing. Its functions include hours, minutes, central seconds and a large date display. The big-date mechanism uses two separate discs to show the date clearly through one window. Overall, the Calibre 2610 gives this dress watch an interesting combination of traditional mechanical watchmaking and modern technology.

The De Ville X2 Big Date belongs to Omega’s De Ville collection, which has a long history of producing elegant watches. Omega introduced the De Ville name in 1960 as part of the Seamaster collection before establishing it as a separate collection in 1967. The X2 series arrived in the 2000s and took inspiration from the square-case designs of earlier Omega watches, particularly the 1951 Cosmic. Omega introduced the X2 Big Date in 2006, combining vintage-inspired Art Deco styling with its modern Co-Axial movement technology. The name X2 reflects the distinctive combination of Roman and Arabic numerals on the dial and the watch's square case design. Today, the Ref. 7813.50.31 stands out as an unusual chapter in Omega's history, offering a refreshing alternative to more conventional round dress watches.
