This 1947 Omega, Ref. 2658-3, exemplifies post‑war wristwatch design with a restrained, purposeful presence. Its construction reflects the era’s focus on durable, wearable proportions and practical detailing. At its heart sits the Cal. 342 automatic bumper movement, a mechanical solution that bridges manual winding and later rotor automatics and speaks to Omega’s watchmaking continuity. For the contemporary collector, this piece offers a direct mechanical link to mid‑century horology and the tactile character of bumper winding, allowing appreciation of historic engineering alongside everyday wearability.
