Aloha All,

I have always been interested in mechanical watches.  My first real watch was a new Rolex Sub Date circa 1995 (I was in my 20s), and I got back into watch collecting during COVID-19.  My obsession with watches turned into modding watches, and for the past two years, I have been amassing tools and parts in anticipation of taking this hobby to the next level.  My goal is to learn how to service a watch movement and get proficient in restoring vintage watches.  Making the old new again. I recently signed up for the watchfix.com course and am to the point of having broken down a movement.  I look forward to interacting with you all and appreciate your future input.

    • Don't bend it that much so the bellows doesn't close it is a trial and error when it comes to sorting out the sound. To help you could put tiny drops of oil on the wires where they touch. 
    • ...but not too hard like me on a first attempt (see the crack?) 😵:  Mind you, getting a full replacement rotor in NOS condition (you don't want to buy a used one with already worn axle) will set you back several hundred dollars.      PS: here is a nice video on the rotor axle replacement. As @Jon said, it's definitely doable. I was just stupid..   
    • ...and if you haven't found this already, here is the oiling chart: https://miyotamovement.com/product/8215/ --> scroll down to "Parts list/Exploded view" and open the tab.   
    • A worn winding pinion wouldn't release the power, as the click is holding the crown wheel. 
    • The problem with a watch like this is where is the technical information? I wasn't even sure that was even based on anything it looks from the link I have below it is based on a real watch well loosely based so maybe there's technical? https://calibercorner.com/pts-caliber-dg-2813/ There guess the watch company has a tiny bit of technical they acknowledge they made the watch but not seeing any service information? https://miyotamovement.com/product/8215/ I did finally find a service sheet for the watch but as it said in the first link it's not an exact clone so that will be some variations. The problem with the Chinese watches they do not supply any technical information spare parts or anything at all other than a cheap watch Which is fine until you go to service the thing and then they'll be problems. On the other hand there clone of the 6497/6498 pocketwatch is almost identical and that means that there is a Swiss tech sheet available which is very very close unlike here where there'll be some differences Now this is a much better choice for watch as they have a website. I'm attaching the technical information for your watch from the website at least they have a really decent service guide versus the Chinese. https://www.timemodule.com/             8691_276584548-Spare-parts-reference-for-the-Miyota-8205-8215-movement.pdf NH35_PL.pdf NH35_SS.pdf NH35_TG.pdf
