1973 Omega Large 38mm Seamaster Cosmic 2000 Automatic Date Model 166.128 with Silvered DialThis Watch Omega Seamaster Cosmic model 166. 128 from 1973. The stainless steel case has the unique 'Cosmic 2000' waterproof design, (not to be considered as now) where the outer bezel frame and movement are housed in inner sealed tub. The 38mm size forms a great presence on the wrist, which in part is due to the nicely rounded bezel, but also due to the generous size for a watch of this era. Inside is the automatic caliber 1012, fully serviced by us
