Thank you for this it. It just confirmed what I had been reading that the Peacock SL1701 is a Miyota 90xx clone. I needed a new rotor bearing for a VC Offshore clone with a “9015” and when asking vendors about replacement bearings they asked if I wanted to Japanese or “domestic” (Chinese) replacement part. There were musings on this
watchuseek thread about it but little else as conformation. They also make the Peacock branded Patek Philippe 324 clone that has the name Cal SL1258. I reached out to them and they will sell individual movements CNY600/piece for the 324 clone which is hundreds cheaper than finding another parts or donor movement. I was a bit worried about ordering the bearings from them for the “9015” until I saw this so great info. Saved to my photos for future reference.
