Omega Speedmaster Mark 4.5 Automatic Chronograph 40mm

The Omega Speedmaster Mark 4.5, reference 176.0015, is an iconic timepiece from the late 1970s and early 1980s, embodying the Speedmaster line's transition toward more technical and multifunctional designs. Featuring a 40 mm tonneau case in stainless steel, this model stands out for its robustness, ergonomics, and a profile that sits comfortably on the wrist. The black dial houses a well-balanced set of subdials and a central GMT hand, making it one of the most complete Speedmasters of its era. Inside ticks the Omega automatic caliber 1045, based on the Lemania 5100, a movement renowned for its reliability and use in military watches. It offers full chronograph functions, date, day of the week, and second time zone. The functional layout, combined with the sapphire crystal and water resistance to 60 meters, make the Mark 4.5 an ideal timekeeper for both professional use and collectors who value Omega's technical history.
