Omega Seamaster Cosmic Jumbo Moonphase

One of the most captivating and complicated watches of Omega's post-war era, the Cosmic 'Jumbo' Ref. 2485 combines elegant dress watch proportions with one of the brand's most celebrated vintage calendar movements.

Produced in relatively small numbers, these oversized 37mm triple calendar moonphase models are among the most desirable vintage Omegas, offering exceptional wrist presence while retaining classic mid-century styling. The 'Jumbo' designation refers to its generous 37mm 18ct yellow gold case—remarkably large for 1950—and houses the manually wound Omega Calibre 27 DL PC, one of the finest complicated movements of its period.

Dating from 1950, this example features a beautifully balanced silver dial with applied gilt arrowhead and baton hour markers, elegant gilt leaf hands and a blued central pointer date hand. The Italian-language day and month displays add further character and underline the watch's continental heritage, while the moonphase aperture completes one of the most attractive dial layouts of any vintage Omega.

Combining rarity, mechanical sophistication and timeless elegance, the Cosmic "Jumbo" remains a landmark reference within Omega's history and an outstanding opportunity for collectors seeking one of the brand's most charismatic complicated timepieces.
