I am offering for sale my Wittnauer Diver 4000. The watch is in extremely good condition as is evident in the pics. The case is sharp, dial is crisp and the tritium lume has aged to a lovely cream coffee. The watch functions perfectly with the bezel rotating as it should. Maker: Wittnauer Model: Skin Diver Reference: 4000 Year: 1960s Material: Stainless steel Dimensions: 38mm diameter; 11mm thickness Crystal: Plexiglass Lume: Tritium Caliber: Manual-winding caliber C11-KS Lug Width: 19mm It will be sold with the custom green leather strap in the photos. The watch was serviced just before I purchased about three years ago. I am requesting $1,100 USD plus shipping insured via Secursus. I have provided several pictures which have been taken in natural light and only cropped where necessary with no colour manipulation. As always if you require more information or photos I am happy to provide. Thanks you for the spaceOF
