November 1960 ONSA ‘Scaphandrier’ Vintage Super Compressor Diver Watch – ETA Cal. 2453


Out of stock

A rare example of a very early EPSA Super Compressor diver watch from November 1960 by ONSA (Swiss), in all original condition, that has been professionally inspected by Localtime.

This is probably the earliest dated EPSA case I have ever seen. The stainless steel case has not been polished, houses a high-grade 25j automatic ETA Cal. 2453 without date (a rarity in itself) and measures in at 36mm or 39mm including the original cross-threaded crown at 3h. The black gilt dial, bi-directional bezel, domed plexi, original lume and hands are stunning. It is wearing a 19mm handmade Italian premium calf leather strap in cinnamon brown. These straps can also be purchased separately from eBay item number 202481981474.

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 Tropic-style silicone rubber straps: Let’s face it, we all wish we could use the vintage, original type, but they are nowhere to be found anymore. If you do find them, they are very expensive or dry and stiff if they were not properly kept all these years. Not to mention the fact that 22 & 24mm are really rare as hen teeth. I have found these straps to be a good alternative to the vintage tropic straps and very comfortable. They come in 4 sizes (18-20-22-24mm) and with 2 smooth, floating keepers. The straps themselves are black and have a nice tropic pattern on them. Their length is 85mm on the buckle end [including the steel buckle] and 120mm on the tail end; so not short but not too long either. I will include a pair of good quality speed pins too. You can see them in the last photo here purchase them separately from the ‘Accessories & Straps’ product category. 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/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.
