Reto Castellazzi is the originator of "Poor Man's" Watch Forum which has been running since December 2001. He also sells watches, some parts and watchmakers tools.
Reto is one of a number of collectors who are very generous in sharing information, and his RWC pages contain a mine of detail about minor and major watchmaking projects. From how to refurbish fine grained bracelets to changing a battery in a Patek, you'll find these pages interesting and informative.
