As a community of DIYer's does anyone do their own watch repairs here?
How hard can it be?
I took my Casio Edifice to a jewellers for repair today and was quoted £91 for a new winder, glass and general clean.
Watch making tools can be bought fairly cheaply, so if I can find the parts for a reasonable price.....
I'll have a go!
Any advice?
Yes, if you want it to ever work again, pay the £91. Is that really a lot? Figure on £15 for the glass and winder, which leaves £75 for a couple of hours work.
As for how hard can it be, take a look at this photo:

That's the crown, base plate and pinion from an Eta 2824 a very common automatic.
The baseplate is 26mm diameter, 2.97mm thick and you're looking the simplest side. The pinion is 5.6mm diameter, 0.17mm thick and has god knows how many teeth around the edge! I can't pick up the screws without a very fine pair of tweezers.
The only cheap watch tools worth buying are the Jaxa type case back openers and strap changing tool. I took that movement apart using a set of 5 Eclipse screwdrivers that cost £12 at a show, which is probably a third of the normal price(going on what he was charging for common Eclipse stuff)
Before anyone asks no, I had no intention of reassembling this even before I lost some of the smaller bits
