Hello

I recently went to Japan and picked up a Seiko 5626-7111 with the HI-BEAT 5626B movement at a thrift store for around 170 USD. The watch is in an okey condition it ran and had a okey clean dial. Unfortunaly a couple of hours later it stopped and the store ofc had a non return policy.

I had some experience tinkering with the UNITAS 6497 and 6498 and thought that this 5626B could be my next challenge. I dissasembled the movement completely and cleaned it. When I assembled it and lubricated it again, i felt that there was a issue when i tried setting the watch. I then dissasembled the train wheels and noticed that the part called "Large driving wheel and pinions" part 220560 had way to much friction. It would not move, and I was quite stupid and dried to remove the cannon pinion from the wheel, and I ended up breaking the whole wheel. I have searched the web a couple of days now looking for this part, but it seems hard to find. I see that the 5606 uses the same part, so I am considering buying a 5606 movement hoping to find a working part 220560. But does anyone here have this part around. I am based in Norway btw.

Another thing? Do anyone know if the crystal in the 7111 case is glue or pressfitted? Can't seem to find any information on this and if anyone else can reccomend a nice replacement crystal with a beveled edge? I see that some have reccomened the Sternkreuz XMF 300.863, Seiko 300W96GN for the 7110 case, will this fit a 7111 case?

Any help appreciated

Thank you for the guide. Will check it out. So my question is kind of more like "Do anyone have the 220560 part laying around?" :) Or is a good place where i could source it?

I had a quick look on line and I did not find it. Chances are a rare NOS part could cost nearly as much a a used movement. There is a sales section in this forum. You have to ask there, but you need a minimum number of posts before you can place a wanted to buy post.

I have NOS 220560, but you are right. Will probably be cheaper for you to find a parts watch.

Thanks. Just saw the message. Cannot reply to you via pm because I have not posted 5 posts yet. But I will consider the offer, I am looking at spare movements from Japan now.

You can post a wtb even if you have a zero post count but you can't sell/trade with a zero post count.

Do anyone know if the crystal in the 7111 case is glue or pressfitted? Can't seem to find any information on this and if anyone else can reccomend a nice replacement crystal with a beveled edge? I see that some have reccomened the Sternkreuz , Seiko for the 7110 case, will this fit a 7111 case?

I believe the crystal is listed as 300V16GN . The V means it has a ring bonded to the glass, and it is this ring, and not the glass, that the bezel clamps down in place. So the good news is you can use absolutely any 30.0mm crystal, but I'd suggest one with a beveled edge as optically that will help mask the ring - any sternkreuz XMF will work - just get the one that the nearest in height.
The bad news is that you'll have to reuse the ring from the old crystal which can be tough to get off.

I've had good results with this technique, Jake

300v16 is a crystal that is prebonded to the bezel. So it is both glued AND pressfit. When you buy an original 300v16, it will come with the bezel. You then pressfit the entire assembly to your watch.

I recently had to replace a badly scratched crystal in a Grand Seiko.
It was bonded into a silver bezel. Couldn't source the whole thing, and a glass was silly money!
I popped it in a saucepan and slowly brought it too the boil.
After a couple of minutes boiling, it pushed straight out.
Quickly cleaned up any remaining glue with a cocktail stick.
Glued in a Sternkreuz equivalent, looks great.

Hello again,
Thanks for the replies guys! Just got 3 Seiko 5606s and the part 220560 seems to be fine on them all. The problem is that i know think that I managed
to damage the palllet fork, one of the stones looks a bit off. Guess I will have to look for a new one for now, and might as well get a Sternkreuz replacement crystal.

I think i will practice servicing the 5606s, before I revisit the 5626 again.

One of the 5606s I bought is a 5606-7071. This one also have the F3 instruction as the 5626-7111. I think i will try to practice replacing this crystal, before I try doing it on the KS.


I will give you an update later this summer on the project.

Update!

One of the three watches I bought for harvesting the part 220560 was in fairly good condition. So I decided to start working with that watch and really get to know the 56xx series of movements.

I bought this 5606-5000 from Buyee for 2500 yen.

It does not loook like much but under that dirty scratched crystal was a white crisp dial and it also has a working qucikset function!

450067

450068

450069

450071

The final result of the 5606 - 5000. It runs great and is fairly accurate for a 50 year old watch. Working on this watch made me feel a bit more comfortable going back to the 5626B movement.


So I realized the 5626B hairsrping was twisted. I probably mishandled the hairspring when dissasembling the movement. Happily i realized that Cousinsuk had replacements in stock. So I bought one and started to practice removing the balancewheel from the balance cock on an old 5606 movement.

After getting comfortable with the removing and reinstalling the balance a couple of times. I tried to to it on the balance of the 5626B with the new hairspring from CousinsUk and now it runs again!

I put the watch backtogether. Now I only need to glue the new crystal to the old crystal ring. The old crystal is horrible.
