The acrylic fell out. I've seen videos of how to refit round ones, but not rectangular ones. This has a small flange on its base. 

Any suggestions gratefully received. 😊

The flange at the base of the acrylic is too large to fit back into the watch. I think this will involve dressing the flange off, and gluing the acrylic in. 

This is annoying, my mobile lets me know that there was a reply via email. I can read the replyb on the email, but nothing is showing on the forum. sigh.

 

Now on my laptop, and it's the same problem.

I'm pretty sure this should be glued back in and it should just fit right into the case without the need for a press. If it isn't going in then it likely isn't the correct crystal.

If you have the movement model and the two digit case number (eg, L8) on the back of the watch then it should be possible to identify the exact model and then the correct crystal.

I agree with @GuyMontag. This type of crystal should fit snugly into the bezel, and permanently affixed with an adhesive like G-S  Hypo Cement.  Some people like to use a UV curing glue, but I prefer the G-S Hypo cement, because it comes with af very nice fine applicator.

A crystal lift would not be helpful for this type of crystal.  If they were installed correctly, they can usually be removed with moderate pressure for the back side.

    • Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.
    • This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.
    • After a bit further research could it possibly be an AS 970?
    • Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner. 
    • Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
