Selling this vintage Mondaine diver in pretty good shape. It is running on an automatic Mondaine 2752 movement which is based on the ETA 2772 and it is keeping very good time - within 5-8 sec/24hr. The watch had a service by my local watchmaker in September 2018 and has been used now and then since. Measuring approx 37,4 mm in diameter and 12,3 mm thickness with 18 mm lugs. It comes with the tropic strap shown on the pictures. The age of the watch is estimated to be early `70s and if the marking between the lugs ("TB71") has something to do about it - 1971 should be a fair guess. (A few of these has been sold and all have these markings between the lugs - it has also been suggested that this might be some military markings, but I have not been able to find out). The bezel is bi-directional and turns smoothly, but has some wear to it (See pictures). I believe the hands are tritium and the crown has screw down function. This watch has an original 200 meter rating as a diver, but I will advice not to use it as such until it has been pressure tested and at least changed the gaskets, but :  It is a 50 years old vintage watch with a lot of charm and patina and should be treated as such. The Mondaine box which is included is a vintage, generic one - I do not know if this model was delivered with such a box.
