Hi forum members, I found this piece on friday and my research on it has turned out very little info.. Can’t find another like it with sufficient details about it..Age, etc..The movement is a Valjoux 7733, case is really sharp and unpolished..Dial has lovely patina albeit showing some spotting (but this is quite “in” now, no?)... Lovely different coloured tachymeter and telemeter markings.. Anyone out there know more anout this model than me, please chime in!
