Description

Omega Seamaster Ref. 105.005 with Legendary Caliber 321 - Extremely Rare Gold Plated Case

This is an exceptionally rare Omega Seamaster Ref. 105.005, powered by the legendary Caliber 321 manual-winding movement. The Cal. 321 is renowned for its lineage, being the same movement family that powered the Speedmaster during humanity's first moon landing.

This particular reference is a highly limited production model, merging the robust chronograph mechanism, typically found in tool watches, into the elegant Seamaster case. Its production period and numbers were extremely restricted, making it a sought-after piece.

This specific example features an extremely rare gold-plated case, which distinctly sets it apart from stainless steel variants. It possesses a subtle allure and a substantial presence.

Examining the movement reveals beautiful coppery bridges, intricate lever systems, and a gracefully beating balance wheel. It represents not just a mechanical marvel but also the spirit of an era when humanity reached for the stars.
