Omega Chronostop UFO — 1969, Cal. 920
This 1969 Omega Chronostop UFO presents the signature late‑60s profile and a grey sunburst dial with applied indices and tritium plots. The 42 mm stainless steel case with screw back wears with a modern presence while preserving period details such as the signed acrylic crystal and crown. At its heart sits the manual‑wind Cal. 920 (17 jewels, ~21600 vph) with single‑pusher Chronostop timing, freshly serviced and documented. For a contemporary collector, it offers a direct connection to Omega’s technical and aesthetic language of the era, rendered in a wearable, well‑maintained package.
