Hello All

I have a following watch on my bench at the moment. I have successfully opened the case but now I'm facing a problem with stem removal. I have researched a subject prior to posting here and I understand the watch has a split stem which i have never encountered before. I tried pulling it with fingers quite firmly but it didn't go. Can anybody share a technique of how to remove it. I'd  greatly appreciate  help with this as this is my first expensive piece that I'm working on and I can't afford to make a fatal mistake. Thanx in advance

If you are sure of he stem being two pieces.

Pull the stem outmost  as for hour or date set .

Insert your tweerzers as if you are holding the stem with it.push furthure in at some point it will break loose.

The stem may fly to orbit, so avoid getting lost.

Thanx for quick answers. Do you think cannon pinion removal tool will handle the job? It gives me chills when i think i have to do something forcefully. Correct me if I'm wrong ; during the assembly you just slide it back to the socket and the whole gently fits back into movement?

Offcourse if you got nippers OH method is superior.

To reinstal, you got to feel the split in the stem is rightly possioned to mount onto the inner piece. Right you just push instal with bare hand no need for excess force.

Depends how tight it is. I know it sounds drastic what I said on how to remove the stem. Believe me it has always worked for me. If the stem has a little rust around the two-piece separating then it will be hard to pull away. You are correct about putting it back, just a little grease on the beak of the stem will help. If the stem is rusty, it might need replacing.   Here is a photo so you can see what the two piece stem is like.

Omega uses quality sturdy crown.yet canon pinion remover may hurt, crush the crown. If you don,t have a nipper, you can borrow a fork off of dining table.slide the stem through the fork to the end of the fork. Push with thumb behind it, you can put a piece of mask tape for crown restaint.

Low risks braking rusted female stem, or the crown from the stem. This is where OH method is superior, no force on the crown to brake.

Sometimes the inner piece pulled to the outermost position, can be seen under the dial. In which case and if the stem is rusty , weak.you can position the male and female parts ( with the crown and stem in place ) so to slide the male part in female part. This eleminates the risk of breaking.

It is not as bad as you feel about it, easy and little risk.

I use a small pair of side cutters. Similar to OH method but with the flat of the side cutters against the cased the crown pulled out, slowly close the side cutters and the beveled side of the side cutters slowly & safely separates the stem. No drama, no worries.

    • Thanks for that Andy, Yes the new bracelet is worth more than the watch itself, Its one I have bought to service and clean-up and on-sell it as a project, look it may sell to someone who has a small wrist, I think I will buy an extender and may-be offer it up with a normal strap as well CJ
    • Not always that simple. Typically the only reason we would have any way of identifying a watch is if parts were available at any time and somebody had a parts reference book then they would help you to identify the watches that they have parts or. Unfortunately there are hundreds of thousands of watch movements with no identification and of course typically no parts the classic place were watches would be identified would be under the balance wheel and your pictures don't really show a good view of that. Occasionally I've seen watches marked under one of the plates. They felt very proud of their watch is a very prominent Swiss company and they ask he stamped the bottom of a plate so you have disassembled find it. Then there is the other system the keyless parts make up something called the fingerprint system but you still haven't given us enough information to make use of that. Here's an image showing what a fingerprint system looks like. The PDF is based on the physical book the physical book has sizes of watches these are smaller ladies watches and keyless parts which in the physical book are printed at the actual size of the watch parts. So to identify with the keyless we need in your case diameter measured on the dial side and a good picture of the keyless parts and then you have to hope that this was made within the right time span of the books that have this system on the other hand a lot of times on the dial side they will also put markings. So basically to identify a movement it has to come out of the case and has to be disassembled.
    • The strap is a 44Q6JB and hadn't realised how much they'd gone up in price. The used one I've got is very worn but may have other links floating around.
    • @Mercurial is this also a variation of the tool you posted? 
    • Thanks Andy, The bracelet is sized very small, around a 14cm wrist. Were would one try to source original links, I guess they wouldn't be cheap if found. The bracelet end links have 4406 B-E stamped on them, is this the Seiko Bracelet code ?? CJ
