1980’s AQUALUNG 200m Professional Diver Date Steel Watch – Japan Seiko Cal. VX42


Out of stock

A nice example of a  pre-owned AQUALUNG 200m Professional diving watch that has been professionally inspected in-house by Localtime and received a brand new glass.

The stainless steel case has not been polished, houses a Japan Quartz Seiko Cal. VX42 movement with date at 3h and measures in at 43mm or 44mm including the screw-in crown at 4h. Beautiful black dial, ratcheting bezel and hands. It is wearing a new vintage-style ‘ladder’ strap that I also sell separately in my store under item 401545611463 in 10 colours and 3 sizes [20-22-24mm]. More details about these straps can be seen if you scroll down the listing to the last photo. 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.

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 9 colours [black, blue, brown, green, orange, turquoise, yellow, white and red; navy blue is on its way]. 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. They can be purchased separately in my store under item 401545611463. 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.
