Yes, it may need a service. Checked with my local watchmaker, and he wants $65.00 just to look at the watch! I got this watch very cheap and for resale. So, must give up looking for a crown stem, which would cost $11.00! Too much to invest for a Franken watch. Will put it on eBay.Sounds like it just needs a service, but hard to know beyond that.
How do you do this? What gear? Do you have an illustration. OK, say it runs, how do I remove the broken threaded part of the stem? Not sure if you can see from my photo, but the space where there should be a release for the crown stem there is a screw! I don't mind "playing" around with the movement, but I do not know what to do at this point. I did watch a video on the disassembly of the 3602 that may help.What happens if you manually wind the spring via the gear? it might just not run because of of an unwound spring.
Thanks for your reply. I tried to shake out the broken off stem as suggested, but it would not come out. Even with the video I don't think I want to take the watch apart. I don't have the tools or the skills to do it. Under the circumstances will try to sell the watch to someone who can get it working or use it for parts.
try to turn it gently, make sure the ratchet wheel clicks. Perhaps you need to remove the gear on the left of it. that screw is marked with 3 slots. Turn opposite way as normal so right turn to unscrew. When wound a couple of turns, nudge the balance to see if it starts. *notice this is not professional advice but rather a butchers trial and error.
If that works and the watch starts ticking, spend the $11 on the stem. Start the disassembly video, loosen the stem holding screw. shake to try to get the remaining stem out. If that fails follow the video to disassemble the stem area and remove piece by hand. Place back and insert new stem and crown. tighten the stem screw to avoid it falling out. As long as you leave the balance alone, you should be able to do it yourself!
