This is the steel version of the GST Chronograph from International Watch Company, better known as IWC.  Model reference 3707 08.


While this watch does come with a service box and guarantee card, the guarantee card is poorly filled out.  The serial number is correct, but the model is recorded as 3707 08 instead of 03, and the date part is not completed at all.  However, the model reference was around in the early 2000’s until about 2005, so circa 2002 feel right.


The GST model was available in either titanium or steel, and strangely the steel version was more money – titanium is a light and very hard material that takes more tooling to make.  However the steel models tend to look better with age.  Unlike the sister watch, the Fliegerchronograph, that shares the same movement, the GST has the cursive text at the top and only came with a bracelet.  It is important to ensure the bracelet is long enough, as many have been shortened over time, and this should fit most wrists.  If not, our sister website,, may have extra links if required.  The automatic movement is based on the Valjoux 7750, so ongoing spares should you ever need any should be easy to source.  All is working correctly of course, and it is nicely finished.    Condition wise there is little negative to report – some very minor marks on the non crown side if you look very carefully, and a tiny dink near the top pusher, but otherwise as nice as you might hope for.

This watch will be supplied with an IWC service box, the original guarantee card and our Certificate of Authenticity.
