Omega Chronostop Genève Single-Pusher Chronograph (Ref. 146010)

Partially verified

This Omega Chronostop Genève is a single-push-button chronograph wristwatch dating to 1968 according to the dealer. Housed in a tonneau-shaped stainless steel case measuring 35 mm by 39 mm by 11.5 mm with a screw-down back and Hesalite crystal, the watch displays a dark gray dial with the 12 o'clock marker offset by 90 degrees. It features applied hour markers with tritium lume, luminous hands, an orange central chronograph hand, and a date window positioned at 3 o'clock relative to dial orientation. The source reports that it is powered by a manual-winding Omega caliber 920 movement providing a 60-second stop function.
