Overview

In the incredible history of Omega, the early 1950s represent a true golden age. The brand was at the absolute zenith of its powers, producing millions of exceptionally high-quality timepieces that would solidify its reputation as one of the finest watch manufactures in the world. This beautiful automatic watch is a perfect, quintessential example of that celebrated era.

At the heart of this timepiece beats one of the most charming and historically significant mechanisms in all of vintage watchmaking: the “bumper” automatic movement. As Omega’s first generation of self-winding calibers, these were true pioneers. Unlike a modern rotor that spins a full 360 degrees, the oscillating weight—or hammer—on a bumper movement swings back and forth through a limited arc, gently “bumping” off two small buffer springs to wind the watch. It’s a robust and reliable system that produces a unique, tactile sensation on the wrist—a subtle bump that is a direct, tangible connection to a pivotal moment in horological history.

This particular example, a Reference 2635 powered by the excellent Caliber 351, dates to circa 1952 and is a stunning expression of mid-century design. The silvered dial has aged beautifully and features a classic and highly desirable “quadrant” layout, with a handsome mix of applied, stylized Arabic numerals at the poles and sharp, faceted arrowhead markers in between. It’s a perfectly balanced, legible, and timeless design. This is all housed in a classic stainless steel case with elegant, sweeping lugs that give the watch a fantastic presence on the wrist.
