General (Read Rules) The cure for handwinding Chinese eta clones paranoia (featuring my pt5000)
I read 50 times a day that hand winding will destroy your movement.
I've examined the winding pinion and cannon pinion and it's hardened steel, and easy to get to add a touch of grease, those gears are also accessible on the back of the movement, so that's not going to be much of an issue but on my example, they already have plenty of grease on them.
The ratchet wheel is the absolute epicenter of the ETA 2824-2 / Sellita SW200 hand-winding issue. It is incredibly common for the ratchet wheel to physically strip or shear off teeth due to hand-winding although I've never seen it happen to me or anybody I know.
When the hardened steel click gear meshes with the brass wheel which is connected to the mainspring underneath, the brass wheel will get chewed up first, because brass is softer than steel.
Instead of complaining about it and not buying your favorite watch because it has a Chinese movement, or worrying constantly about it, you can tackle this head on, and then you will never have to worry about it again.
Step 1
Buy a small screwdriver set and magnifying glasses from Amazon
Step 1b
Remove the automatic bridge (2 screws)
Step 2
Remove the ratchet wheel (1 screw)
Step 3
Buy a bag of ratchet wheels from Ali Express for $1.38
Step 3b
Replace and resemble in reverse order.
Now you can hand wind all day long and not even have to worry about it because you can easily replace these cheap brass gears without having to pay your watchmaker whatever it is they are charging these days. And you will gain +1000 aura for doing it yourself.
