WTT - Vintage Wyler Incaflex Dynawind Heavy Duty 660 diver in TZ excellent condition. Watch is completely original including its gorgeous explorer type dial, with Arabic numerals at 12, 3, 6 and 9 and coffin shaped markers at every hour, mercedes hand set, with lollipop seconds hand, large "W" crown and thick domed acrylic crystal. Timekeeping of the Wyler decorated ETA automatic movement is spot on, but service history is unknown. Lume still charges and glows/dies at an even rate for all markers. I'm actually amazed with the accuracy of the movement. Case measures 35-36mm without the crown and the numbers inscribed on the case back are 8181-1168, so I'm thinking that the watch dates to 1968, but not completely sure. It will come on a like new, period correct rubber basket weave Tropic strap. Will trade for a very nice Seiko 6309-7049. Please email me at: [email protected] if interested in trading.
