Flashman Posted August 12, 2008 Report Share Posted August 12, 2008 Hi, Does anyone know the proper measurement for the strap lug size of the 3717 Spitfire Chrono. I think it is 21mm but I have seen some 22mm straps for IWC too. Just want to make sure I get the right fit. Tom PS If anyone has a spare brown IWC leather strap for sale I would be interested.....

Flashman Posted August 12, 2008 Author Report Share Posted August 12, 2008 21/18 is the correct size Thanks Dluddy, I will have a hunt on the interweb for a decent strap seller, I have checked Bob Straps, and Panertime but they do not have much of a selection, in those sizes or one that looks like the OEM. I'm not looking to spend much on it either. Quote Link to comment Share on other sites More sharing options...
