This Omega Seamaster Cosmic 2000 (Ref. 166135) dates from the 1970s and presents as a larger “jumbo” 38mm wristwatch of its era. Its case proportions and design reflect the transitional aesthetic of late 20th-century sports-dress watches, engineered for daily wear. Powering the watch is the Cal.1012 movement, a period-correct calibre that speaks to Omega’s technical continuity through decades of mechanical development. For the contemporary collector, this Seamaster offers historical character and wearable presence, representing a clear link between classic design language and robust mid-century watchmaking.
