The quickset date function works flawlessly by moving the hour hand repeatedly between the 20.5 and 24 hour marks until the desired date has been reached. After winding the sharply threaded, non-screwdown crown 39 full revolutions the movement had an impressive power reserve of approximately 40 hours, losing about 2 minutes during this time.Given that the movement runs a bit slow and considering that it shows no signs of ever having been serviced (there are no watchmaker service markings on the inside of the case back) a complete overhaul is recommended. This watch measures approximately 36 mm excluding the crown, approximately 38.5 mm including the crown and approximately 20 mm between the lugs.
Case thickness, measured from the bottom of the case back to the top of the bezel, is approximately 8 mm. Including the crystal case thickness measures approximately 11 mm. Given that the movement runs a bit slow and considering that it has likely never been serviced a complete overhaul is recommended. As such no warranties, express or implied, are 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.
