Probably around 1970 or so, it has the earlier (and better) Calibre 752 movement, looks nice and they tend to be a good watch to wear if you like the style.
dial is nice, hands correct and look the right age. Case is a bit too polished, but the sunburst can be restored easily by someone who knows what they're doing.
very classical example of Dynamic watch, with the numbers on the movement and in the case one can easily find the correct year .. of course, it means open the watch from the front ... blow the crystal away .. not for everyone !
