On offer is a stunning vintage manual-wind OMEGA Art Deco square tank watch with ref. 6515823 dating from the early 1920s (the movement's serial number pegs its production date at 1923), crafted in 14K gold with intricate filigree engraving along the bezel and sides. The dial is a classic white with Arabic numerals and a dedicated sub-seconds dial at the 6 o'clock position. The watch features distinctive blue steel Cathedral hands. It measures 26mm in width and 32mm from lug to lug, and weighs 29gm including the band. It is in excellent cosmetic condition with minimal signs of wear (see photos). A certified Omega watchmaker confirmed that the watch is indeed 14K gold. It winds smoothly and runs like a charm, albeit slightly faster than normal (less than 5 minutes per 24 hour at the time of listing). The watch was serviced a number of years ago and fitted with a new band, but left unworn since then. Insured shipping with tracking.
