DOXA (Swiss) SUB 300T ‘Sharkhunter’ Diving Watch For Aqualung U.S. Divers Co. – ETA Cal. 2472


1 in stock

From the early to mid-1970’s an exceptional ‘Sharkhunter’ SUB 300T diver from DOXA’s (Swiss) Synchron SA era, issued for Aqualung U.S. Divers Co., that has been professionally serviced by Localtime.

The large C-Type stainless steel case is in excellent condition, houses an ETA Cal. 2472 with date and measures in at 42mm or 45mm including the DOXA-logoed crown at 3h. The signature black dial, set of 3 hands and bezel are simply stunning. It is in excellent vintage original condition and is wearing a quick release black FKM ‘Summit’ strap. I have included many photos of the watch and also some closeup snapshots I took just for fun and to allow you to enjoy the lovely details of this fine timepiece. At the end you will also see some photos taken on the watchmaker’s bench. Given the earlier DOXA dial and crown vs the Synchron-signed case, I would consider this a ‘transitional’ model between the DOXA and SYNCHRON eras of DOXA SUBs, something that we saw quite often as companies used all the parts they had available during those times. In simpler terms, Synchron used a dial and crown they already had in stock from the previous ‘DOXA SA’ era with a case they had produced with the Synchron name.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 3-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

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.
