Runs strong with both the day and date wheels rolling over as they should occasionally and inconsistently the movement slows by several minutes in the middle of the night, likely leading up to the day and date wheels rolling over. When this happens I’ll reset the time in the morning and it’ll resume keeping accurate time. Given that the movement shows no clear signs of ever having been serviced a complete overhaul is recommended. This vintage Chronosport S. Day-date has a matte black “T-SWISS MADE-T” 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 ratchets counterclockwise, has lots of character and presents beautifully. The coated all stainless steel case shows minor wear with some loss of coating. The outer edge of the case back is stamped “ALL STAINLESS STEEL SWISS MADE 30 ATM/1000 FEET 186 682″ with “3218” stamped along the inner edge. The inside of the case back is stamped “BREVET + 503305″ followed by M. SA, SWITZERLAND, CHRONOSPORT, INC. The crystal shows light scratching that is nearly visually imperceptible in person. The 1 jewel unadjusted Swiss “CHRONOSPORT” stamped ETA 555.125 quartz controlled hacking movement with quickset day and date functions runs strong and keeps accurate time. However, occasionally and inconsistently the movement slows by several minutes in the middle of the night, likely leading up to the day and date wheels rolling over. The quickset date function works flawlessly by pulling out the crown to the first position and turning it clockwise. The quickset day function works in the precisely the same manner with the exception of the crown being turned counterclockwise. The screwdown crown, which shows wear, unscrews and screws back down without issue. Given the mentioned issue and considering that the movement shows no clear signs of ever having been serviced a complete overhaul is recommended. This watch measures approximately 41 mm excluding the crown, approximately 45 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 9.5 mm. The crystal adds no measurable thickness. This watch comes on what I believe to be the original canvas strap, which is in great condition. I have an old Chronosport brochure that shows the S. Being offered on either a bracelet or canvas strap (which looks identical to this one). Given that the movement occasionally and inconsistently loses time in the middle of the night and considering that it likely has 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, which were taken in natural light and from various angles, as they are part of the description and serve as an accurate representation of the condition of this watch. While the movement runs strong with both the day and date wheels rolling over as they should occasionally and inconsistently the movement slows by several minutes in the middle of the night, likely leading up to the day and date wheels rolling over.
