1960’s DESOTOS (Swiss) Grenoble Olympic 300m HRV Diving Watch – Felsa Cal. 4007N


1 in stock

A wonderful example of a rare DESOTOS (Swiss) Grenoble Olympic 300m HRV diving watch that has been professionally inspected in-house by Localtime.

The case has not been polished, houses an automatic Felsa Cal. 4007N with date at 3h and measures in at 41mm at the bezel and 44mm including the screw-in HRV crown at 3h. The stunning sunburst brown/grey dial, bi-directional bezel, new plexi, applied indices and hands (the red lollipop sweep is gorgeous!) are just stunning. It is wearing one of my own Localtime silicone ‘waffle’ rubber straps in brown that in my humble opinion, compliments the watch quite nicely (listed separately in my store). I have included many photos, including some closeup snapshots I took just for fun, to allow you to enjoy the lovely details of this fine timepiece.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 6-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Extra: Try also my Localtime FKM Waffle-style straps (last photo here), now available in 9 colours and listed separately in my store.

Important Note: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I mention what has been changed (if anything) on the watch and I include a written warranty with my listed price.

Important Note On Straps/Bracelets: The straps I use on my watches (leather, canvas, suede, rubber) are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
