Interesting vintage Wyler auto/date, in steel case and with original dial. Wyler used a unique shock resistance system called Incaflex whereby the balance wheel was sprung by long elastic balance shanks. In advertising as early as 1948 they claimed theirs to be “The world’s only watch with the self-protecting heart”. The 17 jewel self winding movement is an ETA cal 2479, case is marked Wyler Incaflex, Stainless Steel, and “waterproof” on the back (markings are faint, not visible in photo). This vintage timepiece is in excellent working condition, is fit as found with a period tapered stainless steel Kestenmade mesh bracelet. Photos are not actual size of watch, it measures 31 mm across (not including crown) x 36 mm lug to lug.
