IWC 3717 Spitfire Chrono Strap

[Flashman]

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.

PS If anyone has a spare brown IWC leather strap for sale I would be interested.....

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.
