·No big fights or UFC on the tube last night, so after the kid went to sleep I spent a satisfying evening taking apart this seiko and rebuilding it. Didn't break anything, didn't lose any thing...that's a win!

·Congratulations, Seikos have an unusual auto wind mechanism, but they are not too difficult to work on. They are very well-made, rugged watches.
Although I'm primarily a vintage Hamilton and Omega collector, I have more vintage Seikos in my collection than anything else.

·I had never worked with a Japanese-design before-- mostly Swiss, Russian, a couple of American movements. It was very user friendly and I was impressed with the economy of the parts and construction. For example, check out the holes in the wheels on the bottom left-- uses a lot less material.
I didn't take out the mainspring, but I imagine it need replacing since the amplitude is very low.

·Impressive. We’re you using a schematic or manual to assist?

·Nope. But I took pictures as I dissembled it to make sure everything went back in the right place/order.

It's very very gratifying (and at times incredibly frustrating) and I recommend any watch person to try their hand at it. Even picking up a $5 A. Shield movement on Ebay and disassembling it is fascinating.

·Here, check this one out from a couple of months ago. I got this for $0.99 and cleaned up really nicely:

Low amplitude is a Seiko hallmark. Not sure what the numbers were, but it's not unusual for the amplitudes to be much lower than on an equivalent Swiss movement. You typically won't be getting 300 degrees with a new mainspring...unless you put a much stronger one in than it's meant to take (not recommending this by the way).
Cheers, Al
