A 1947 Omega Jumbo with calibre 265
This large 1947 Omega Jumbo presents a refined, purposeful case and generous 38,5mm presence that speaks to postwar watch design. Its construction houses Omega’s celebrated calibre 265 (30T2), a robust hand-wound movement known for reliable timekeeping and traditional finishing. The combination of timeless case proportions and a proven manual movement offers a tactile connection to mid‑20th century watchmaking. For a contemporary collector, the watch delivers historical character and mechanical clarity—an elegant daily-wear example of period engineering and understated design.
