This Wittnauer Twin Crown Super Compressor, Ref 8007, was the 1960s cousin to the very desirable Longines 7150 Super Compressor. It’s in excellent condition for its age. Here are the key specs – stainless steel 36mm case (almost 40 mm with twin crowns), clear acrylic crystal, and 17 jewel C11KAS movement serviced in 2013 when purchased from a forum member. The dial and hands match very nice nicely and the tritium is still active. The twin crowns are signed - top crown adjusts the inner bezel and lower crown adjust time (with date quickset) and winds the watch. It comes on a new padded genuine shark strap with box and accessories (general warranty with quick date set instructions and other booklets). Available for $1,750 and includes shipping CONUS. Sale is final unless the description is not correctly presented. Lots of references available.
