I sent it back to the factory Anonimo, now in Switzerland. That rumour has been circulating for a while but I can assure you they have all the parts and and revisions. In fact that strap was purchased from them as well.
In my case, the patented crown lock had come apart (missing pin/screw) which was impossible to source. I even called a supplier in singapore that wanted close to 1500 for it. But rest assured, Anonimo is and will continue to service even the older calibers.
