Can anyone help me figure out how to fix this watch? I had seen a video that said it was likely that Center screw being loose so it wouldn't wind, but even after tightening that it won't start ticking. Bought some simple tools and I'm willing to mess with it (I believe it was a cheap watch) I just have no clue what to do.
Given its a 7s26, unless you want to preserve the authenticity of the watch, its probably better to just replace the movement. its less expensive than having it professionally serviced.
How much would servicing cost vs buying a new movement?
The modern version, NH3x (the last digit varies based on features) can be picked up aftermarket for about $50. The NH (which Seiko also calls 4rxx) is a drop in replacement for the 7s26, but includes handwinding and hacking. These ones from Crystal Times (no affiliation) are also regulated so they are more accurate than what comes from the factory.
You will also need to purchase a new crown stem, and you'll probably want a few tools as well.
A seiko service has to go to an authorized seiko service center to get parts these days, but even a basic service can run over $100
Ok, different watch, but my Seiko kinetic 5M43-0E70 got just a new movement, €135 total at Seiko Nl. I guess a 7S26 or replacement is about the same price.
Btw, the 5M43 is now a 5M83, instead of 1 - 2 weeks power reserve it's now up to 6 months
