1967 Omega Seamaster Chronograph (Ref.105.005) Cal. 321

This Omega Seamaster ref.105.005 is one of the most sought-after vintage Omega Seamaster chronographs, this reference houses the Omega 321-caliber movement which is loved by enthusiasts for its superior performance and durability that is not found in some of the later production chronograph caliber movements. The same cal. 321 movement can also be found in the Omega Speedmaster Professional or "Moonwatch". The Omega cal. 321 was in production for roughly only 11 years as the superior production of the cal. 321 was cost-prohibitive and eventually replaced. Making the ref. 105.005 from a horological perspective that much more limited and ultimately rare.

This specific Omega Seamaster ref 105.005 would make a wonderful addition to an existing collection and or make a great daily driver on its original omega beads of rice style bracelet and or on a vintage style leather strap!
