By the 1970s, the Seamaster collection had evolved to include a wide variety of case shapes and dial designs, reflecting the bold aesthetic trends of the decade while maintaining Omega's commitment to mechanical quality. The Caliber 1012 is a respected automatic movement from this era, known for its high beat rate and reliable performance. / Second Vintage SKU: OME-OAS-0023
