Here we have a beautiful example of one of Omegas more quirky sports watches. The Omega Chronostop was first produced in 1966, there were then a number of variations produced until the early 70s.The Cal 865 is a manually wound complicated watch, with a 'half chroograph' function. This is basically a simplified version of the famous cal 861 that was used in the late 60s Speedmasters. The orange hand can be instantly reset by pressing and releasing the top pusher (and paused whle pressed in), though there is no elapsed time dial as you woud find on a standard chronograph watch. this means timing anything over 1 minute is difficult. Its likely this was originally made as a stop watch for short events, but also the use of just one button which resets and starts makes it more usable as a lap timer than a traditional chronograph.


This example is an early reference 145.009, made in 1968 and has a lot to offer for its relatively modest price point.

The orange hands adds some brightness to the grey dial, while the polished steel applied hour markers give it some depth. The hour and minute hands are also so bold and originally had a very strong lume. There is also a racing style seconds track which display increments of 0.2 seconds so more accurate readings can be given when the second hand is paused.

The case is not overlly wide from 3-6 measuring at 33m excluding the crown though it has a tonneau case so has a bigger feel on the wrist.

The stainless steel case is polished with a screw down case back.

We have fitted an aftermarket mesh steel bracelet with a deployant buckle.
