Complete with the instructions, this ChronOris men’s chronograph is also on the Oris bracelet.

HOW DO WE DATE THIS WATCH?

There are no serial numbers to date Oris by, but the ChronOris was launched in 1970 and ran until 1980. Most watches are sold in the biggest numbers close to the launch date, so we think this is from circa 1971.

CONDITION

This is the original model that the new, £1,450 ChronOris is based. The idea may have been based on the Omega Chronostop, another 60 second timer in the market just before the Oris was launched. Unlike the Omega, the Oris has an internal bezel that is set via the crown at 3 – the crown at 4 winds the watch and sets the time. The pusher at 2 starts, stops and resets the stopwatch. The original instructions to operate the 17 jewel calibre 725 movement are included, and must be quite rare in themselves. The case is chromed, but in good overall condition with just slight wear around the lugs but the graining around the bezel is clearly visible, showing it has not been polished. The chrome has faded off the crowns and pusher though. The bracelet is stainless steel and has been cleaned in our ultrasonic bath, and has the signed Oris clasp. The dial is good with just very slight marks, and the pop of orange on the hour markers and chrono hand lifts the design up.

This watch will be supplied with our branded presentation box, original instructions and our Certificate of Authenticity.
