NOS 1960’s BERIOS [A&A Gilomen SA] Steel Skin Diver 17j AS Cal. 1780/81 With Date


Out of stock

A beautiful example of a BERIOS (A&A Gilomen SA) NOS steel mid-size skin diver with the 17j manual-wind AS Cal. 1780/81 with date, that has been professionally inspected by Localtime.

The brushed steel case is in excellent condition and measures in at 32mm or 35mm including the crown at 3h. The black dial with 24h zulu-time markings, bi-directional black/red ‘coke’ elapsed-time bezel, domed plexi, wonderful lume and hands are lovely. It is wearing one of my own waffle-type black rubber straps with red stitching that, in my humble opinion, compliments the watch quite nicely. These straps can be purchased separately here: 202061460884. 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 that are handled by Localtime, the BIN price includes a written 6-month written warrantee from the date of purchase. Feel free to contact me for whatever questions you might have.

Important Note On Condition: 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.

Extra: Try my Localtime vintage-style Ladder-Type straps! I have found these straps to be an excellent value and very comfortable indeed. They come in 3 sizes [20-22-24mm] and have 2 floating keepers. They come in 7 colours [black, blue, brown, green, orange, turquoise and yellow]. Their length is 95mm on the buckle end [including the steel, screw-in buckle] and 135mm on the tail end. I will include a pair of good quality spring bars with each strap. Feel free to contact me for whatever questions you might have. You can see them in the photo here below and they can be purchased separately from my eBay store under eBay item number 401545611463.
