While the movement runs strong and keeps accurate time and the roulette (black even, red odd) date wheel rolls over when the quickset function is used, the date wheel will not roll over automatically on its own. Given this and considering that the movement has likely never been serviced a complete overhaul is recommended. This seldom seen vintage PAT diver has a matte black “EBAUCHE SUISSE” signed dial that is in pristine condition, free of any scratching, tool marks, chipping or defects. The original lume, which remains fully intact and emits a quick-burst glow after being exposed to bright light, has aged to a perfectly matching warm buttermilk hue. The bezel, which does not rotate likely due to gunk buildup underneath, looks good. The all stainless steel case is in excellent condition showing minor wear and no signs of oxidation. The outer edge of the case back is stamped “ALL STAINLESS STEEL 100% WATERPROOF TESTED 20 ATM ANTIMAGNETIC” with “21631” stamped in the center. The crystal shows scratching. While I normally show pictures of the movements of watches that I put up for sale, the case back on this one is torqued to what feels like factory specs and is too tight for me to remove. A skilled watchmaker will have no issues removing it. The automatic movement with quickset date function runs strong and keeps accurate time but the date wheel does not automatically roll over on its own as it should. However, the quickset date function works flawlessly by pulling out the sharply threaded, non-screwdown crown to the first position and then turning it clockwise until the desired date has been reached. After recently winding the crown 39 full revolutions the movement had an impressive power reserve of approximately 41 hours. The crown winds beautifully. Given that the date wheel does not roll over on its own and considering that the movement has likely never been serviced a complete overhaul is recommended. This watch measures approximately 37 mm excluding the crown, approximately 40 mm including the crown and approximately 19 mm between the lugs. Case thickness, measured from the bottom of the case back to the top of the bezel, is approximately 8.5 mm. Including the crystal case thickness measures approximately 11 mm. Although the movement runs strong and keeps accurate time, given that the date wheel does not roll over on its own and considering that the movement has likely never been serviced a complete overhaul is recommended. As such there are no warranties, express or implied, attached with the sale of this watch. Vintage means old and while my personal belief is that old-school means better quality and workmanship, things can and do go wrong from time to time. Any servicing costs going forward are your responsibility. And please study the 12 high magnification pictures carefully as they are part of the description and serve as an accurate representation of the condition of this watch.
