1960’s EXACTUS (Swiss) 38mm Steel Diver Watch Radium Dial – 17j Automatic Felsa Cal. 1560


1 in stock

A lovely example of an early radium dial diving watch by EXACTUS, that has been professionally serviced by Localtime.

The large, 38mm Aquastar-style stainless steel case houses an automatic Felsa Cal. 1560. The black radium dial shows the distinct 4 metal triangle indices at 3-6-9-12 which were the norm for radium dials at the time and its in decent condition given its age (radium dials by their very nature did not survive well especially if they had humidity issues in the past. The watch is wearing a same-period stainless steel bracelet that I think fits it quite nicely.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 6-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Information about the Localtime straps: Handmade in Italy from premium calf leather and to our own specifications, they come in 5 sizes (lug width/buckle width): 18/16, 19/16, 20/16, 21/18 and 22/18mm & 11 colours. We sell these separately in our store and you can also see them in the last photo here.

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.
