FOR PARTS/REPAIR – The caliber 613 manual wind movement runs for a few seconds at a time only when the time is being set. The time sets without issue and the crown winds smoothly. The crown action likely suggests that the mainspring needs to be replaced. Given this and considering that the movement shows no signs of ever having been serviced at a minimum a compete overhaul is required. This seldom seen vintage 1960’s Perlow Winton Skin Diver, which came from the estate of its original owner, has under the damaged crystal a pristine glossy black “SWISS” only signed Explorer-style chapter ring dial. Any imperfections seen are on the crystal. The original lume, which remains fully intact and no longer glows after being exposed to bright light, has aged gracefully to a golden buttermilk hue. The beautifully cut all stainless steel midsize case shows honest wear and minor signs of oxidation. The outer edge of the case back is stamped ALL STAINLESS STEEL – WATER RESISTANT – INCABLOC – NON MAGNETIC – SWISS. ” The inside of the case back is stamped “WINTON WATCH Co” followed by “SWISS” and “2494. The crystal likely needs to be replaced as it shows scratching and cloudiness on its underbelly. The 17 jewels unadjusted Swiss “WINTON WATCH Co” stamped caliber 613 manual wind movement runs for a few seconds at a time only when the time is being set. Given this and considering that the movement shows no signs of ever having been serviced at a minimum a complete overhaul is required. This watch measures approximately 33 mm excluding the crown, approximately 35.5 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 fixed bezel, is approximately 7 mm. Including the crystal thickness measures approximately 10 mm. The lug to lug distance measures approximately 42 mm. At a minimum a complete overhaul is required. 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 24 high magnification pictures carefully as they are part of the description and serve as an accurate representation of the condition of this watch.
