Mobilization‑era Omega from 1939
This Omega, dated circa 1939, exemplifies late‑1930s mobilization‑era wristwatch design with a compact 31 mm steel case and period‑correct details. The original dial and acrylic crystal retain the watch’s historical character, while a calf leather strap suits its proportions. At its heart is the manual caliber 26.5 SOB T3 with 15 jewels, a movement type that reflects Omega’s focus on reliable, serviceable mechanics of the era. Recently serviced (08-06-2026), the watch pairs historical context and solid construction, appealing to collectors who appreciate well-documented pre‑war mechanical pieces.
