Would anyone happen to know if a stem from Cousins would include the rubber o ring or if this would have to be bought separately? The parts diagram I have doesn't show a part number for the o ring and the parts description on Cousins doesn't say whether it comes with an o ring or not!

Typically as stem does not come with the crown. The crown is where you'd find the  O-ring or gasket crown gasket perhaps would be a better name typically that's found in or on the crown. So if you're replacing a stem. Typically replacing the crown also.

Then as you found out a stem is part of a watch movement. A crown is a casing components you'll need a case number to figure out which crown you need.

Then depending upon the type of crown sometimes they do make generic O-rings to replace the one that's damaged if that's the problem?

Ah I see! The problem I have is that the watch case let water in. The case back seal was damaged but upon further inspection I've also found that the stem is very slightly bent, the crown rotates in an eccentric movement when turning, so I'm assuming the seal may not be sealing the case also. I'll have a look again when I get home but it looked like the seal sits on the stem so I assumed it would be a stem part! I'll try and find case parts 😫

I take it the gasket on the stem is sealing inside the case tube as opposed to a crown gasket that seals on the outside of the case tube.

If i can suggest posting a picture of both the case design and the stem that you have.  Pictures pictures Pictures,  always pictures. A picture paints a thousand words 🙂

I've rechecked and it appears John is right! The seal is on the crown. I didn't realise the crown had a shaft that screwed onto the stem with a seal in the middle which goes inside the case. I assumed the crown was flat and the threads of the stem screwed into it. Can you tell I've never removed a crown before 🤣 thanks for the help guys!

If it actually is the stem itself bent you could replace the stem keep the crown and change the gasket. But a lot of times it's the crown that gets bent. Then the other problem is gaskets just have a way of going out with time and require replacement.

Here is a typical image of a crown that citizen and Seiko typically have. With crowns like this the gasket is replaceable.

    • 0.3mm hole drilled which was surprisingly easy and went a whole lot better than i expected considering i did it free hand with a carbide bit in a small pin vice,and no breakages. I only have some 0.34mm and 0.5mm blue steel so my plan is to open up the hole to 0.5mm and reduce the pivot down to size to fit the plate bearing before fitting it in the arbor.  I'm not entirely sure on the hole depth, my head is tell me 3x the hole diameter . I dont have a 0.4 mm Nev or i would have.  Turn a new arbor 😲😵 me thinks you overestimate my ability Nev 😅
    • I have never understood how a square can be produced on a lathe, seen plenty of videos but not sure how it works. How do you make the huck on the arbor?
    • personally from my point of view I would say no. This is where more than just an evaluation on one side is needed somebody needs to take the watch apart and see what else is bad. Like it's possible the pivots for those wheels are missing which we really can't see in the picture right now. Then that does appear to be rather heavy rust on the balance bridge and I wonder where else were going to find that rust? just a little clarification here are you new to working on an Omega 1010 watches or are you new to working on watches altogether? The reason I need the clarification is that if you're new to watches and even if this watch came to you for free repairing it is going to be extremely expensive as Omega watches tend to be very expensive for spare parts. you never can tell about watch companies what part numbers we can find.of course the biggest problem of all is this is Omega watch part of Swatch group and Swatch group doesn't like us so they're not going to sell you the spare parts unless you have a swatch account. then if you have to find aftermarket Omega parts because they know that nobody can get those parts that tend to be really expensive is why repairing Omega watches is going to be very expensive. According to the parts list found at the link below there were some jewels available I'm not sure if they're the right one because I haven't quite figured out which jewels those are yet. I'm also attaching a PDF of the parts list to help you identify whatever it is you're going to need it looks like some of the plates were once available although getting a new plates will be problematic it might actually be better to find a scrap watch to steel parts from.   http://cgi.julesborel.com/cgi-bin/matcgi2?ref=OME_1010       Omega 1010_complet_2236.pdf
    • You mean all that stuff about aliens and black helicopters isn't true?
    • Thanks yes it’s nice to make tools and equipment if we can , I needed a fixed steady for my Pultra I had one for a Pultra with 70mm centre  and I was going to cut it down to be able to use it on my P type ( 50mm centre) but it seemed a shame to butcher such a rare item so made one. Dell
