Omega - A steel 'Chronostop Driver Edition' flyback chronograph wristwatch, circa 1967, model 145.010, serial number 25869211, circular grey '12 o'clock at 3 o'clock' dial, with silvered batons, white hands and centre orange chronograph sweep, signed 17 jewel mechanical crown wind movement calibre 865, with crown at 1H and start/stop/reset pusher at 11H, case, 35mm diameter, to a black strap with pin buckle Omega first released the Chronostop in 1966, and it was well regarded within the watch industry - it won the 1967 Honour Prize for “Chronographs and Sport Watches”, sponsored by the Swiss Watchmaking Federation, and also took the first prize for Industrial Aesthetics at the Utrecht Spring Fair in 1968. It was selected as the official Omega timer at the Pan-American Games in Winnipeg and the 1968 Olympic Games in Mexico. Unlike conventional chronographs that record seconds, minutes, and hours with two or three subdials, the Chronostop was designed to be used for short interval timing - less than one minute - with a sweep hand for seconds and a single pusher. Pressing the pusher starts the timing hand, pressing again and holding stops the hand, and releasing will return the hand to the 12 o’clock position. The 145.010 is the most sought after of the 'Chronostop' series and was designed specifically for rally drivers. The dial has been moved through 90 degrees and the watch is worn under the wrist, allowing the driver to glance down at the time without having to remove the hands from the steering wheel. It was a unique attempt by Omega to completely change how a wristwatch was worn, and is now a rare and collectable item.
