Omega Bumper Automatic Reference 2375 (Steel)
Ref 1100
A highly attractive 1940s Omega bumper-automatic wristwatch, Reference 2375, presented in a stainless-steel case with refined mid-century proportions and elegant vintage character. Measuring 32.5mm (excluding crown) with a 39.7mm lug-to-lug span and a 17mm lug width, the watch wears with classic understated presence, reflecting the design language of early Omega automatic dress watches.
At its heart is Omega’s Calibre 28.10, a 17-jewel bumper-automatic movement signed and numbered by Omega. This early automatic calibre features the distinctive “bumper” winding system, where the rotor oscillates in a back-and-forth motion against spring bumpers rather than a full 360-degree rotation. A significant development in Omega’s automatic watchmaking history, the Calibre 28.10 is valued for its robust construction, smooth operation, and importance as one of the brand’s pioneering self-winding movements of the 1940s.
The dial is a standout feature, presented in a rare gilt finish with elegant Roman numerals and a subsidiary seconds display at 6 o’clock. Signed Omega above the centre, the dial retains strong vintage character and warmth, enhanced by the refined typography and balanced layout typical of the period.
The stainless-steel case preserves clean lines and classic mid-century styling, housing the early automatic movement securely within a well-proportioned design. Overall, this is a highly appealing example of Omega’s early automatic watchmaking, combining technical innovation with distinctive dial aesthetics and wearable vintage dimensions.
This watch is fitted with a brown Hirsch strap and an aftermarket Omega-style buckle. Each of our watches is carefully cleaned and serviced by an experienced watchmaker to ensure reliable performance while preserving its vintage character. For added peace of mind, it is supplied complete with a 12-month mechanical warranty and a new presentation box.
