The Omega Ref. 2505-4, powered by the caliber 266 and bearing a serial in the 13xxxxx range, is an exceptional example of Omega’s post-war production, dating to around 1952–1953. With its 37 mm stainless steel case, it was unusually large for the time, offering a bold wrist presence that today feels perfectly contemporary while still carrying the charm of early 1950s design.

At its core beats the hand-wound caliber 266, part of Omega’s celebrated 30 mm movement family, renowned for its reliability, robust construction, and precision. Collectors widely regard the 30T2-based calibers, including the 266, as milestones in 20th-century watchmaking, thanks to their durability and their role in cementing Omega’s reputation as one of the world’s most respected manufacturers.

The reference 2505-4 is characterized by its clean, balanced silver numerals layouts and elongated lugs, which enhance both elegance and wearability. Its understated design makes it versatile: refined enough to complement formal attire, yet robust in size and presence for everyday wear.

As a timepiece from the early 1950s, this Omega captures the spirit of an era when the brand was establishing itself as a leader in both design and technical innovation. The combination of its oversized case, historically important movement, and period-correct serial makes this example a highly desirable piece for collectors who appreciate authenticity, originality, and the enduring style of vintage Omega.
