Omega - Jumbo Cal.265 - 2503-12 - Uomo - 1950-1959

Omega Jumbo “Blue Marble Dial” – Secondi Subsidiari – Cal. 265 – Ref. 2503-12 – Vintage 1950s

The Omega Ref. 2503-12 is a beautiful example of Omega’s classic 1950s watchmaking, combining traditional Swiss mechanical craftsmanship with the elegant proportions of a vintage Jumbo dress watch. Powered by the reliable Omega Calibre 265 manual-winding movement, this model represents the timeless appeal of Omega’s early mechanical timepieces.

This particular example features a striking blue marble-effect dial, decorated with irregular turquoise and lighter blue patterns that create a distinctive textured appearance. The oversized Arabic numerals, elegant gold-tone hands, and small-seconds subdial at 6 o’clock complement its classic stainless-steel case. A matching blue textured leather strap completes its unique vintage character.

Important Photo & Color Note: High-resolution images may exaggerate minor imperfections not visible to the naked eye. Photographs were taken using professional camera equipment and controlled lighting; therefore, the dial, case, and strap may appear slightly darker, brighter, or different in tone depending on ambient lighting, direct sunlight, viewing angle, and screen settings.
