Hello Another Valjoux 72 chronograph, but this time it's something unusual and from a brand that had made very beautiful diving watches and which had made very high quality automatic and manual movements before be bought by the Swatchgroup in 1984 and follow up with entry level ETA. This is the Certina Chronolympic chrono from 1971. Pictures from the seller, I will post mine as soon as it arrives. Have a nice week Very best regards Georges
