Same here, but it fouls on the inside of the crystal, so I'm assuming it should be a little deeper.
 

Looking at Stian's video, it does seem like it should go on a bit further, but his also springs in the same as mine, so maybe not?

 

Yes, just as in the video, with the retaining spring sitting on the sloped shoulder of the seconds arbor.

Okay, I adjusted the hands a bit and everything seems okay now. It sets a lot more easily than I'd expect, but I'm hoping that's just how this movement is. It's running in now.

 

 

You need a holder with the center support. Doesn't have to be Bergeon and some are available by 3d printing. The screw on the bottom and hole on the sides are to see that the adjustment is correct. I think I bought mine specifically for the 1001.  Hand setting holder.or something like that.

[SwissSeiko]

you can also do this on a staking tool. although its a bit cumbersome. You use a stump to support the back of the seconds pinion. I'm in the process of making a stake that is threaded to accept different tips to press the hands on.

[Razz]

If it's not the Canon pinion it could be something with the minute wheel pinion for why the minute hand is not moving but the hour hand does. Here is a dial side shot without the calendar works on my dirty 1001 (later cleaned up) if that helps.

So Stian is wrong in saying the automatic module bridge will hold the center seconds pinion in place?

Thanks, @JohnR725, that makes sense with regard to the bushing.

Those instructions then imply the hands must be fitted before installing the automatic bridge, otherwise there's no way to support the seconds pinion.

Now I've just got to find a movement holder.

Found this which may guide you in your search.

These look a bit more reasonable, if suitable and you don't mind a wait? The largest is stated to be for a Rolex 1570 which is a 12.5''', same as the Omega 1001.

Hey thanks! I don't think the Rolex ones will work because the screw is too blunt. That pinion is recessed pretty well in the movement.

However, as I'm here in the states, Esslinger has a version of that Bergeon holder available, which looks like it'll work. Interestingly the same part number as the Bergeon.

Borel do them as well but they're currently out of stock.

I would err on the side of caution and use the holder. Yes. And the convention is to remove and add the automatic works while the movement is in the case, so yes put the hands on, Case the movement and then put the automatic works on if you can. My case for my 1001 doesn't work that way so I have to add the autoworks on before casing. I think this is one of the reasons this movement gets a bad rap from watchmakers, the awkwardness of the casing.

Those instructions

Yes one of the unfortunate problems and watch repair is missing technical information. With the early days stuff was scanned solely for parts and they deliberately skipped over anything technical like servicing. Then we have some companies putting stuff in separate documents which of course had nothing to do with parts so they never were scanned. Then today where they don't want to share the documentation at all. Which makes doing a watch like this extremely problematic if you don't have the supplemental information.

Are the centre screws interchangeable between sizes? 

The Chinese jewel press kit I got has a set of movement holders, though only up to 11 1/2 ligne.

It's less than two of the branded holders. You could use one of the centre screws in the larger cheap holder?

£82 for a reasonable jewel press with holders and hand fitting tips..

Cousins UK has the Bergeon 12.5 ligne #M0981 for £46.75. There might be a less expensive option.

Make sure you get the 12.5 ligne for the 1001 movement!

Coincidentally, £46.75 converts to $60.95 right now, so I'm okay with that price. It's on its way to me right now.

Okay, the problem was the center cannon being too loose on the wheel. I didn't have a cannon tightener, so I ground two broken stakes on my little belt sander, then stoned them.

I didn't have a rod that fit inside perfectly, so I had to just be extra gentle with my tapping. After a couple taps, it popped right on with a good amount of friction.

That's as much stress as I have in me tonight, so it's red wine time until I find another free hour.

Nicely done msb, accurate grinding of your stakes

Did you also broach it out to size with a mini lightsaber at the same time ? It takes a lot to impress me , but you achieved it matey.......Very Cool indeed

Hah! Sadly, no. My mini lightsaber is in the shop.

I did realize I wouldn't be able to broach it, so I was very gentle and got lucky on the first try.

This is one of those times where you shouldn't trust the aliexpress copy and buy Swiss if you want to keep your fingers & eyebrows.

It matches the two brain cells I have to rub together, apparently I'm a little dense these days.

Finally got it back together. I have to say, a pretty nice result.

Love the integrated bracelet and round dial. I found an advertisement from the time period somewhere touting the high beat and the first of its kind integrated bracelet of this watch. I have the square dial version and the case has 4 screws and much harder to do simple rate adjustments without taking it completely out of the case.
