Ebel watch straps seem to be like hens teeth now! My wife has a 15 year old Ebel 1911 and it is almost impossible to find a new leather strap for it. And we go through this problem every couple of years or so! Can anybody point me in the right direction (I live in London). I would even be prepared to change it to a metal strap if I could find one.It has a 13mm band width and the watch has a 27mm diameter at its widest.
