Making Case Press Die?

I'm having trouble closing a small fashion snapback - just as I had trouble opening it. I believe that is because the case back is oval and slightly raised in the center, so the die presses there, making it flex instead of pressing down the edges.

 

Has anyone had luck building a custom die from hard wood, filed to push just the edge of the case back?

Hi jdm,

 

I've had this problem many times especially with larger diameter watches & using nylon dies, the dies tend to flex like a diaphragm absorbing the force of the press. I have improvised with wood & it works, always a relief when the back snaps on though !.  Good luck !

Thanks, in my case (no pun intended) it's the case back that flexes, as the die is thick and strong despite being inadequate. I'll see what can I do with wood then. This is certainly an hobby of thousand trades.

I think your diagnosis is probably correct. I have found that a tiny bit of silicone grease on then rim really helps.

      Black coating on shock jewel metal housing

      Do you use an ultrasonic cleaner or a watch cleaning machine? I've been considering trying out the L&R liquids you mention in my "ancient" Elma watch cleaning machine. However, I worry that these liquids are too toxic and smell too much without adequate ventilation. Where I live it is normally too cold to work with this outdoors, but a few months a year it could work. At some point, I tried Elma's Suprol Pro and almost passed out from the fumes. It comes with a "narcotic effect" warning. How bad are the L&R fluids in this respect?

      I've removed the movement and left it on a windowsill. I'm in north east England, so not very sunny today 😥 however I'll give it a few days and then try a new battery. The document you sent claims the movement is the same as the C700 with regards to parts and assembly. I've managed to find an exploded view of a C700 and some troubleshooting instructions. So if a new battery doesn't work in a few days I'll strip the watch and test the electronic circuit unit. No doubt it will require cleaning and oiling anyway. Thanks again for your help @watchweasol

      Hi. That explains it, done that myself.  Leve the movement open with the back off and battery out for a few days in the sun and let it dry naturally, re fit new battery and try again if  it is not successful the circuit block may be toast,  Better if you can get the movement out of the case for drying what is your location

      Thanks for that. He's worn the watch daily for the last 20 years, he said he didn't even think about it being on his wrist, because it's always there. He had a shower and when he got out he noticed the crystal has condensation on the inside. I may have exaggerated when I said it was FULL of water 😅 I removed the movement from the case last night and there's no sign of water on the coil or battery, however the dial has dried water spots on it. I'm not sure about stripping the movement further, I've never done anything with a quartz movement. I tried looking for a donor movement but they seem to be practically non existent. Even Jules Borel doesn't list this movement in their parts catalogue
