Automatics: .......a Question .....
I was just explaing how watches are powered, and realized that I really didn't know how to explaing how a self-winder runs ......felt kinda stupid, so it's time for another of Salleh's stupid questions ! How does a self-winder work ? I know that with a quartz watch it's the battery that powers the watch ....and a winding watch is powered by the unwinding of the mainspring....( at least I hope that's how it's done, that's what I been thinking all these years) ....if someone can put it in simple terms, how does that automatic that I dearly love work anyway ? oh and I am speaking of the simple types not the ones that work on the $10,000 watches ....I live and sell in the world of $200 watches.....

AR Coating on PO8500 - how durable is it?
Recently I saw a FS post that the seller had declared there are scratches on the AR coating when viewed from an angle.I wonder how durable/resilient is the AR outer coating on the PO?I have a habit of rinsing my watches with mild soap and water after wearing. To dry it, I clean it with an old face towel. Will this action be harmful to the AR coating?Thanks!

The case was neither badly scratched nor dented, but appeared to have some dinks here and there from daily use. The breaking of the glass caused it to get in contact with the hour and minute pointers which got bent out of shape from the top toward the dial (from outside to inside along their length). The dial got scratched due to the broken glass.The watch was brought to the main AD of PP in Switzerland at the Bahnhofstrasse in Zurich who could not perform the repairs in their own little atelier. They sent it to PP in Geneva for repair. After two months the first call was made to the AD to enquire about the state of repairs. The status was unknown and we were told to call in a week. One week later the answer was that the watch was still being repaired, with no further details. About tw
