A lovely and beautiful example of an ISOMAX [by Aureole SA, La Chaux-de-Fonds, Swiss] 20ATM aquastar-case diver watch that has been professionally inspected by Localtime.

The case has not been polished, houses a 25j automatic Felsa Cal. 4007N with a red date wheel at 3h and measures in at 38mm or 41mm including the crown at 3h. The stunning black Tritium dial, bi-directional inverse-elapsed-time [countdown] bezel, original domed plexi and gorgeous hands are stunning. It is wearing a NOS Tropic-style rubber strap in black that, in my opinion, compliments the watch quite nicely. 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: 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.

EXTRA! Check out the Localtime ‘waffle’ type rubber straps: I have found these straps to be very comfortable and a great match especially for sporty or diver watches. They come in 4 sizes [16-18-20-22mm], 6 colours of rubber [black, blue, brown, orange, red and yellow] and 6 different colours of stitching [white, grey, blue, orange, yellow and red]. The straps themselves have a ‘waffle’ pattern on top and a ‘grooved’ pattern on the bottom. Their length is 97mm on the buckle end [including the steel buckle] and 118mm on the tail end; so not short but not too long either. They have two floating keepers with the same rubber ‘waffle’ pattern. A good quality pair of spring bars is included 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   202061460884.
