AS 1187/94 How to find a stem

[GonzaV]

Hi everyone,

Sorry if this seems like a dumb question, but I have restored this watch and the stem broke. I’m very happy that I was able to bring it back, but sadly I’m a newbie and messed up the stem. 
I’ve had trouble trying to identity the movement. I try typing stem for AS 1187/94 and I’m not sure if that is the correct way of naming the movement. You can see it in the picture near the balance. Thank you so much for any wisdom so I may continue in this beautiful world of watch service apprenticeship.

If you look for AS1187, you should be able to find it. I've done a quick search and have found several suppliers.

What would you name this one? I get confused because it has what it looks like two sets of numbers to me. Would this be a AS 1187 or AS 1194? Any wisdom on how to read these calibers would be nice. Thank you so much for your response. Cheers!

1187/94 apparantly means it's used for both the 1187 and the 1194. The difference might be one has a complication the other has not? They have the same winding stem:

The difference between the 1187 & 1194 is the size 10.5 & 11.5 so it's unusual to see both markings on the plate as this is the main difference.

It would help to know where in the world you are so people can advise a suitable supplier.

Yes this is a peculiar watch because there's a sizing difference as opposed to other things that would make a difference.

Not necessary but it makes it easier to look at is you can trim off all the unnecessary stuff on eBay listing. If you find the item number and then trim off starting with the? And everything else.

Yes it's usually helpful of people would have some sort of location with their profile to make recommendations.

Then at the link below is a nice source of looking up cross references for parts etc. and as sometimes as common with watches like this lots of variations of the stem. Including oversize ones for the plates that may be worn out. Then looks like your stems discontinued which is really an issue because they're recommending the best fit part number which does appear to be in stock.

I suggested that an introduction with basic information such as, experience and location should be compulsory but it was deemed unnecessary.

Yes the classic problem of you can't please everybody and somebody will be unhappy about something. Then one of the problems with experience is how you know if you're experienced or not? Yes I know on paper it seems like a simple question with answer but for a lot of people that are in isolated or basically an online discussion group you don't necessarily have a good way of telling your skill set with anybody else's skill set. So while you may seem to be extremely experienced the reality is you may not be. Or people at seemingly think they're not experience may still have way way more experience and others. Or the greatest amusement I have on this group is you can be voted number one on a regular basis and not necessarily be super experienced but only because you're taking part in all the discussions can you get a lot of thumbs up now making you the most experienced person on the board without necessarily being the most experienced.

Then unfortunately even though we would like to know a location I find a lot of people want to order from cousins even if they are in the US. But still it would help for things like eBay is to build the point out a country for eBay purchases as shipping can get expensive when ordering from obscure sellers

The thing that seems to have been overlooked here is what Tap size is actually required?

Not entirely is why when I snipped out the image I included all the variations. Then usually tap 10 is the standard but there are a lot of variations with this particular watch.

It's just your wording that seems to point the OP in the direction of the Tap 10.

From an economics/production perspective it makes sense to do this. You'd just have to make one design and one set of tooling to get two different sized movements. You only make the large size and perform one simple turning operation to get the smaller one. Neat! Haven't seen that before.
