This Omega Speedmaster 125 is a self-winding, water-resistant gentleman's wristwatch, produced in the 1970s. The watch features a tonneau-shaped, three-body stainless steel case measuring 42 x 51 mm, with both polished and brushed surfaces.

It is equipped with an integrated stainless steel bracelet and a screwed-down case back adorned with a logo. The flat crystal incorporates an outer tachometer graduation. The black dial contains tritium-coated indexes and a date aperture. Complications include auxiliary dials for the seconds, the 12-hour register, and a 24-hour indicator, along with a 60-minute register operated by a fourth central cross-shaped hand.

The movement is the copper-colored Caliber 1041, which is a 22-jewel automatic movement featuring a straight-line lever escapement, a shock absorber, a monometallic balance, and a self-compensating flat balance spring. The movement is adjusted to temperature and five positions.
