Seiko Spring Drive

I was hoping to see some repair videos, or movement reviews on this variety of watch movement, however, I can't seem to find any here. Youtube does have one build video of these watches by a factory rep in a jewelry store.

There are many technical reviews on the net for Seiko Spring Drive. I recall a very good one with detailed pictures which was done at an American horological academy few years ago, you should be able to find it with Google. 

The reason why there are no repair or service articles is that by one side the owners are unwilling to give the watch to anyone but Seiko, and on the other hand even competent watchmaker are unwilling to touch these, as they are unfamiliar with them and would not get parts from Seiko.

In fact even Seiko service centers anywhere In the world will send to Japan the Grand Seiko, Credor or Spring Drive models given to them for service or repair.

Right, even parts to the bracelette, Damaged bracelette on mine, I am not going to pay an arm and a leg.

    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
    • Well I’ve never seen the make before and cannot find any info, I haven’t got it just yet it’s been left to me among a 1970’s sea master and a mid size yeoman. But if anyone has any information on this one please feel free to enlighten me, many thanks
