What about it

Featuring a captivating radial sunburst gold dial complemented by a vibrant sangria red bezel, this watch brings a fresh and exhilarating energy. Oh, the difference it makes!

In the latter part of the 1960s, Omega envisioned the incorporation of a new model into the Speedmaster collection. The tonneau-shaped case epitomizes the aesthetics of the late 1960s and early 1970s with precision. Notably, its design marked a departure from the traditional lyre-lugged Speedmaster Professional, boasting a considerably more contemporary appearance. It is crucial to acknowledge that the Speedmaster Mark II held official recognition as a Speedmaster Professional, a designation explicitly stated on its dial.

The dial of this particular Mark II iteration bears a striking resemblance to the gold variant of reference 145.006/016. Furthermore, Omega extended its foray into gold Speedmasters with the BA 145.022 model.

There was also 18K gold version.

Omega caliber 861

Lemania created a family of cam switching chronograph movements in the 1960s just as chronograph watches were becoming more popular in the mass market. The Lemania Calibre 1873 was part of a family of similar 12 ligne movements, running at 21,600 A/h and lacking modern features like hacking seconds or automatic winding. In 1968, Omega selected the Lemania 1873 as the basis for their Cal. 861, used in the Omega Speedmaster Professional line of watches. These feature a 30 minute chronograph counter at 3:00, a 12 hour counter at 6:00, and small seconds at 9:00.
