DOXA (Swiss) by Synchron SA SUB 300T ‘Searambler’ Diving Watch – ETA Cal. 2872


Out of stock

From the late 1970’s an exceptional ‘Searambler’ SUB 300T diver from DOXA’s [Swiss] Synchron SA era, that has been professionally restored and fully serviced by Localtime.

The large C-Type stainless steel case is in excellent condition, houses an ETA Cal. 2872 with date and measures in at 42mm or 45mm including the crown at 3h. The signature silver dial, set of 3 hands and bezel are simply stunning. Later SUB models like this one, had wider lume indices on the dial and also had aluminum bezel inserts. It is wearing one of my own ladder type silicone rubber straps in green. I have included many photos of the watch, some snapshots from the restoration but also some closeup snapshots I took just for fun and to allow you to enjoy the lovely details of this fine timepiece. Also included is a photo from my store Doxa display, for presentation purposes.

As with all the watches that are handled by Localtime, the BIN price includes a 6-month written warranty from the date of purchase. 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 warranty with my buy it now price and I always describe what I have changed, if anything, on the watch. In this case, the only thing to mention is that the bezel is a bit stiff. Other than that, the watch is is stunning condition.

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 Ladder-Type Vintage-Style silicone 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 10 colours [Black, Blue, Brown, Green, Orange, Turquoise, Yellow, Red and White with Navy Blue coming in stock at the end of the month]. Their length is 95mm on the buckle end [including the steel, screw-in buckle] and 135mm on the tail end. They are listed separately in my store. I will include a pair of good quality spring bars with each strap. Feel free to contact me for whatever questions you might have.
