Ronin Posted February 18, 2013 Report Share Posted February 18, 2013 I stumpled upon an eBay sale of 1570 powered watch that much to my surprise had a 1520 Balance installed in it. After some Google searching, another thread was discovered on TRF which appears to support its intechangeability. (Both 1570 & 1520 - 19,800BPH) Based on this information, if you should find yourself DIY servicing a 1570, and say don't want to mess with the micro-stella regulating tool-- a 1520 Balance can be dropped in and regulated like the ETA & Miyota(based) movements we are used to regulating. Now I realize this is probably a sin to many, but it does provide options. Thoughts? Quote Link to comment Share on other sites More sharing options...
freddy333 Posted February 19, 2013 Report Share Posted February 19, 2013 The Microstella system is better than most non-Microstella systems in that it allows a much finer adjustment, but I guess if you have no other choice. Quote Link to comment Share on other sites More sharing options...
