OmegaThis Omega Speedmaster Professional, reference 145.022, is a hand-wound chronograph wristwatch. Introduced in the late 1960s as a successor to the reference 145.012, this model marked the transition from the calibre 321 to the calibre 861 movement.
The 42 mm stainless steel case features a "Straight Writing" case back, characterized by the linear engraving around the Seahorse medallion. The black pie-pan dial includes white printed text and aged yellow lume. The watch is fitted with a tachymeter bezel containing the "dot next to 90" detail. The handset remains original in style, though the hands have been relumed with Super-LumiNova. The piece is accompanied by a Bulang & Sons Racing Brown leather strap.
The auction description reports that the movement was fully serviced by their watchmaker.

Design
- Movement
- This reference utilizes the calibre 861, a manually wound, cam-actuated chronograph movement. This calibre replaced the earlier calibre 321 in the late 1960s production run. According to the auction description, the movement serial number is 3219xxxx, which dates the watch to 1970. The watch has undergone service by the vendor's watchmaker and remains in functional condition.
- Case and Dial
- The watch is housed in a 42 mm stainless steel case, which retains much of its original factory finishing. The black pie-pan dial features white printed text and yellow-patinated luminous material. The handset is of the original style, although the auction description reports that the hands have been relumed with Super-LumiNova at a later stage, matching the dial's patina. The external tachymeter bezel displays the "dot next to 90" configuration and has faded to a grey tone. The case back features the "Straight Writing" engraving, denoting the specific arrangement of text surrounding the Seahorse medallion.
