1960’s LA MARTINE By Ardath Reef-Diver Submarine 666ft Diver Watch ETA Cal. 2452 With Date


Out of stock

A wonderful example of a rare LA MARTINE (Cesare Zanardi) ‘Reef-Diver’ 666ft cushion-case diver watch by ARDATH, that has been professionally inspected by Localtime.

The case has not been polished, houses an automatic ETA Cal. 2452 with date at 3h and measures in at 41mm or 42.50mm including the very rarely seen ‘bayonet-type’ crown at 3h. The silver dial, bi-directional bezel, original domed plexi, applied indices and hands are stunning. It is wearing a lovely same-period BOR bracelet that, in my humble opinion, compliments the watch quite nicely. The same ARDATH model is listed separately in my store. I have included many photos, including some closeup snapshots I took just for fun and some from the service bench, to allow you to enjoy the lovely details of this fine timepiece.

As with all the watches that are handled by Localtime, the listed price includes a written 6-month written warranty from the date of purchase. Feel free to contact me for whatever questions you might have.

Extra: Try my Localtime Glove-Grain premium calf leather straps: I have found them to be very comfortable and a great match especially for dress watches or chronograph watches that will combine well with this style of straps. They come in 3 sizes [18-20-22mm], 6 colours and have colour-matching stitching on top and an extra stitching on the back side. Their length is approximately 88mm on the buckle end [including the silver-coloured buckle and 115mm on the tail end; so not short but not too long either. They have two keepers, one of them is fixed and the other one is floating, for a better fit and comfort. They are listed separately under eBay item number 132797421296 and you can also see them in the last photo here. A good quality pair of spring bars is included with each strap. Feel free to contact me for whatever questions you might have.

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 include a written warrantee with my buy it now price and I always describe what I have changed, if anything, on the watch.

Important Note On Straps/BraceletsThe 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.
