1967 Omega Seamaster Chronograph (Ref.105.005) Cal. 321 B.O.R. Bracelet

This Omega Seamaster (Ref.105.005) is one of the most sought-after vintage Omega Seamaster chronographs. This specific reference houses the Omega 321-caliber movement. This movement is one of Omega's most sought after movements due to the superior performance and durability not found in some of the later production chronograph caliber movements. This same 321 cal. movement can also be found in the Omega Speedmaster Professional or "Moonwatch". The Omega cal. 321 was in production for roughly 11 years as the cost of producing this specific movement was cost prohibitive making this piece from a horological perspective that much more limited and ultimately rare altogether. The dial is gorgeous and possesses a patina that can only be achieved from years of proper use.
