Manufactured in the early 1960s, this is a rare unpolished Omega chronograph equipped with the renowned Caliber 320 and featuring a silver dial.
The distinctive stainless steel case with twisted lugs—different from later models—along with the alpha hands shared with contemporary Speedmasters, beautifully captures the design character of the era. The unpolished condition enhances its exceptional vintage presence.
It houses the Caliber 320, a two-register version of the famed Caliber 321 used in the Speedmaster. Since three-register chronographs were the mainstream configuration at Omega during this period, models with two registers are particularly scarce. The clean, elegant look unique to the two-register chronograph adds to its appeal.
