Object description

Case and Dial Construction

The watch is housed in an asymmetrical stainless steel case characterized by twisted lugs. The case is described as being in an unpolished condition, retaining its factory-applied finishing and sharp edges. The external features include an original luminova-filled bezel, which is reported to be in near-perfect condition, aside from a minor area of delamination located at the 40-minute marker.

The matte black dial features applied luminova plots which exhibit a soft green color. It is paired with a set of sword-style hands, also featuring luminova that is noted to match the dial closely in appearance, though slightly brighter in tone. The case back retains its original factory engravings.

Origin and Assembly

This timepiece was assembled by the Australian firm WatchCo, which was historically an authorized Omega service center. Following changes to Omega's authorized servicing, WatchCo utilized its existing stock of vintage service parts to build complete watches.

The assembly process involves the use of genuine Omega service components, including the case, bezel, crown, dial, and hands. These are combined with a refurbished Omega movement dated to the 1960s. The resulting timepiece is described as a functional integration of modern service parts and period-correct mechanical elements, intended to provide the experience of operating a vintage dive watch.
