Omega Chronostop Blue Dial

Omega Chronostop Blue Dial

The Chronostop is an interesting side note in the history of Omega chronographs.

Manufactured in the late 1960s-1970s with a few different case orientations and movements, the Chronostop offered the functionality of a 60-second stopwatch feature, operated from the single pusher located above the crown. These watches were designed to be worn under the wrist, making them popular with drivers. The Chronostop introduced a press and release stop-second feature, engaged by the single pusher at 2 o'clock.  To start the chronograph, the single pusher is depressed.  To stop it, the pusher is depressed and held, and then released to reset.

This particular example is completely original, driven by the Calibre 865 manual-wound movement, and features nicely patinated blue dial with original handset.  Its size, dial design, and unique functionality make it an interesting conversation piece and collectable timepiece.
