Hello all, I have been struggling to find a replacement stem and crown for a pocket chronograph that I have running a valjoux 9 movement.  Since the piece did not come with one to begin with, I don't have the stem measurements.  If anyone has any suggestions for me I would greatly appreciate it.  The outer measurement of the crown tube is 8mm and it is supposed to have a pusher type crown that has a button in the center to activate the chronograph.

I don't know the answer here but wanted to mention that most members consider polite to use the dedicated section to introduce oneself before asking questions.

Hello,

I didn't work on such a movement yet, but at Ranfft it looks like the Valjoux 9 is a member of the Valjoux 5 family and may have the same stem W1730.

There is a seller in germany who has it on his list:

Hope this helps a bit.

    • Hi friends! My mother got a bunch of old watches from a horologist who was retiring, and he subsequently passed away. It's been in her studio for years, and she showed it to me today and I just fell in love with it. Sadly, I don't know a darn thing about it yet. It's quite old, or at least seems to be. It has two winding arbors, but the key is missing. The crystal appears to be some kind of yellowed plastic, which is odd- I think it was replaced at some point to possibly protect it or something. If I had to guess, it's from the mid-19th century, given that it has no keyless works and that it says "Anchor Escapement" in French. It looks to be about 18 ligne, and the case fob is positioned in the upper right corner. The face is missing the dial, the hands, and a couple of the wheels that drive the hands- I think. But the movement itself seems to be in excellent shape. The serial number on the movement matches the number on the case- it's stamped on the movement and on the case in two places. I haven't started any disassembly yet, but I'm wondering if anyone can give me some idea of what kind of movement it is, and where I might look to see what parts are missing from the face. i may even have a dial that would fit it. It's in good enough shape that I think I could get it running, assuming I could find the missing parts. Any insights are vastly appreciated and thank you!
    • I’ve watched every video I can find on YouTube. Some of the info is contradictory and none mention  the effect on amplitude or spring coil spacing which I observed. I was hoping someone here is a Seiko expert and knows these inside out.   
    • This video explains how to set up and adjust the etachron regulator :   I hope that helps, Mark
    • This eBay listing seems to verify that the watch disassembles as I suggested : here. The display caseback is held by the section that pushes out of the outermost rear bezel.  The movement seems to be a Ronda 1113. Best Regards, Mark
    • Decided to update with the repaired watch back in rotation and the new anniversary gift.
