This is the queen of all toolwatches in the rare olive green execution. The IWC Compass, Porsche Design (Ref. IW3510) from the 1980s.
The olive green coated 39mm aluminium case comes with several innovative patents that you will only find in this watch. First of all the integrated compass with mirror, which can be found by unfolding the top part of the watch, locked by two buttons. We also need to mention the ultralight integrated bracelet linksystem, sidekicked with a very special slide-clasp-lock contruction, and can also be completely separated into two bracelet-halves via a second mechanical solution. The watch with a hight of only 13mm, considered it´s exclusive function, wears very comfortable and looks just awesome on the wrist.
The IwC is in all original and unmolested condition with some patina signs on case and bracelet and a dial and handset with beautifully toned original tritium. the IWC automatic caliber 375 is running exact and strong, just like all other functions of the watch do. it currently fits wrist up to 17,5 cm circumference or smaller. This olivegreen version of the 3510 is a true collectors watch and very hard to find nowadays.
