Dating from 1942, the Omega chronograph ref. CK2078 is a rare wartime piece in stainless steel. It is defined by sharp faceted lugs and a charcoal grey dial, a combination highly regarded by collectors of 1940s chronographs. Inside beats the calibre 28.9 CHRO, a column-wheel chronograph movement from Omega's early golden era. Presented in excellent condition on a leather strap, this CK2078 is a sought-after example of vintage Omega chronographs, predating the Speedmaster by more than a decade.
