Hello, for sale I have a 1970's Wyler Incaflex Lifeguard 660 divers watch, with the famous and collectable Wyler miss-print dial “Heaty Duty Diver”. I have had this watch in storage for a long time and its time to find another home, hopefully to someone who appreciates vintage and rare pieces. This watch has a black dial with square white hour markers, red military time markers and white seconds track. Red hour, minute, and seconds hands. Date aperture at three o clock. Inner rotating timing bezel works with top right pusher. Dial is stamped "WYLER INCAFLEX HEATY DUTY DIVER 660". Double signed crowns. Caseback with "Wyler Lifeguard inscription and insignia. The watch has a automatic Swiss Made ETA movement heavily modified by Wyler, you can read up on what Wyler did online, it runs, can be set and timekeeping seems to be fine over a 24 hour period, but service history is not know. I believe these have a ETA 2772. Case is one piece (monocoque) stainless steel. The case has normal wear for age, there are no deep marks or rust. The acrylic crystal, depending on the angle will have visible scratches, which, might be able to be buffed out, it is original since it has the small "W" stamped in the middle. The watch will come on a vintage and rare Kastenmade "Bambi" Made in Japan stainless steel strap, it should fit up tp a 8 inch wrist.See picture for reference of exact watch in Wyler catalog with the three other Lifeguard models of the period.Summary:Wyler Incaflex Dynawind "Heaty Duty" Diver 660 Swiss Made Divers Watch.
