Vintage Buler Divers watch crystal issue

[RyanGreerMcGilloway]

Hello there fellow watch enthusiasts.

 

i have an issue here. The watch is running perfectly without the acrylic crystal on but whenever I press the crystal in place, the movement immediately stops.

 

i believe this is and issue derived from the pressure forcing the movement down and causing it to stop.

i don’t think it’s a case of the hands hitting the glass.

i have proved this by removing the hands.

 

i have been through two high dome crystals now and they don’t work.

 

does anyone have any advise?

The crystal must never touch dial or mov't at all. It should sit on a lip in the case. And this being a diver should have a tension ring or other waterproofing device. Check that carefully.

Never heard of a "tension right". Did you really mean a "tension ring", or am I missing something?

can somebody please forward me an alternate watch acrylic crystal that would satisfy the above.

29mm dia. 

High dome.

Please excuse my spelling error, luckily  I was able to go back and correct it.

The original is a broken peice, but it has no tension ring.

 

It is just Acrylic throughout with a lip on the edge.

That's the important detail, you may need to get a slightly larger crystal and cut it on the lathe (I don't think that can be done without) to re-create the lip, which sits on the top of the case. It may need cement to stay firm and partially waterproof.

Good thing we now have a full hour to correct our little mistakes! Whish we'd have a full day (or more) though! Imagine putting a watch together and only having an hour to correct any mistakes we'd made!

I think the OP needs an inside stepped crystal., not extra high. He should post complete measure and a sketch of the profile

I wonder? Are you pressing in the crystal without taking the movement out? If so i would take the movement out before i do that . And then check if there is anything on the otherside that hits the balance or pressing on the dial . I think it would work with a "normal" ATC crystal. A low dome acrylic with tension ring. Very seldom i use a high dome crystal . At least on divers like this.

You think maybe , he is pressing on the dial face , and compressing then movement?
