ARTEN “Substar” 20ATM Diver UFO Case – ETA Cal. 2782 – Box & Bracelet


Out of stock

This is a wonderful diving watch from the 1970’s with a chunky UFO s/s case [a.k.a. Sealab] that measures in at 38mm or 42mm including the oversize screw-in winding crown. The case stands 48mm long lug to lug. The watch has been professionally restored and fully serviced in-house here in our Localtime Spa.

Everything is original on the watch, including its box and logoed bracelet. The case has been gently washed, not polished. The original plexi has been gently polished. The dial is in exquisite condition. The hands are original and we have re-lumed the hour and minute hands whose lume was damaged, to match the original ‘lollipop’ seconds hand. The watch is fitted with its original stainless steel bracelet and also comes with its box. We have made many photos, including snapshots of the restoration and some fun macro shots we made, just for fun.

Feel free to ask me any information that you might need.
