I have a Wylar 72C Incaflex front loading face. I do not know how to get the stem out in order to replace a gear that fell out, and to re-seat the movement.

Hi  can you remove the back and post a picture of the same. we need to be able to see the movement inorder to help you.   thanks

The attached picture shows crystal removed...front loading, so movement has to come out the front I presume. the movement does lift out part way but stem prevents it from coming out. I cannot get even a razor blade to crack the back.

What you may have is a split stem which is in two parts  and dovetail to getherand inorder to remove the movement the outer part of the stem has to be pulled out.  This has to be done with a tool, bergeon make on specificaly for the job but it can be done with a pair of top cutters,  protect the crown with a piece if cloth or thin leather and grip the crown underneath so as the squeezing action cans up the insie of the jaws drawing the crown out parallel. Its a tricky operation and if not done properly can break the stem

Oh my. This looks like a very challenging service!

I have a valjoux 726 GMT with a broken ratchet wheel. Been broken for 14 months and I still don't think my skills are ready to tackle it. Getting close, I think.

Whoa...this sounds like a job for a pro. Hope I can find a real watch repair person. Thanks for your input.

      How do you thread a screw on the lane without shearing it off?

      By caseback · Posted

      My second suspect would be the O1 tool steel. Is it still "soft" enough after the turning operation? If the part got hot, it might be work hardened, making it more difficult to thread and easier to break.

      Bracelet Extender Sizing

      By Curare · Posted

      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

      Unknown watch movement logo. Very interesting

      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.
