This Omega Seamaster chronograph wristwatch, reference 145.006-68, is crafted from 18k yellow gold. It is powered by a manual-wind Omega calibre 321 movement, bearing the number 20526418.
The watch features a gold dial adorned with applied baton indexes and iconic sword-style hands. The dial layout includes three subsidiary registers, providing readouts for constant seconds, a 30-minute timer, and a 12-hour timer. An outer tachymetric scale is integrated into the dial design for measuring speed over a fixed distance. The watch is presented on a black leather strap equipped with a plated pin buckle. With an approximate size of 36 mm by 43 mm, including the lugs, the timepiece has a gross weight of approximately 75 grams.
The dial, movement, and case are all signed by Omega. The crown is a modern replacement. This vintage chronograph reflects the technical standards and aesthetic design typical of late 1960s Omega production.
