Omega Seamaster Chronostop was produced from the late 1960s through the 1970s, and offered the functionality of a 60-second stopwatch. This feature is operated from a single pusher located above the crown (the first push starts the sweep hand, the second stops and resets it. Despite limited functionality, these watches were useful tools for athletes, drivers, and medical professionals, and sold well during their production run.
This particular piece features an oversized 41mm cushion case (while most Chronostop versions are relatively small), making it an attractive and suitably sized watch for daily wear. It is powered by the manually-wound Omega Cal.865 movement developed specifically for this model.
The watch went through complete service in March 2016.
