Hi folks. I'm trying to track down a replacement glass for a Jaeger Reverso (169x209). It's the older design that requires the glass to be curved top and bottom.. Generic glass is available, but only with a flat bottom. I can't find the curved version anywhere. Any ideas?

If it's completely obsolete, then the only thing I can think to do is mill down the curve on the inside of the case so it will take the flat bottomed glass.

Not him but a few similar. I'll try him as well. That generic glass seems to be in a few places. But I think the company that make it stopped making the curved version, according to Cousins.

Wondering if flattening would be the answer. I just need to plane it down slightly along the indicated line. If the owner agrees...

A hard call but the crystals seems to be flat for that one, but if the owner agrees why not it seems to be enough material left.
Just a qurious question, is it dirt or scratches in the corner of the lover corner part of the case?

This turned out okay. I very carefully filed the curve down flat with an escapement file. It took me three hours because I was being so careful. It was hard to get the angle correct. But the file you can see in the picture did the job really well.

The glass now sits flat and the watch is "upgraded" to accept flat bottomed glass. It just needs some UV glue and she's good to go. Phew!

    • I sure appreciate your comment! I will look into one of those or maybe something similar. I of course will check your video to have a better idea.  by the way, that’s a beautiful lathe! Mine is a little peersless, but I just bought a Boley & Leinen that is on its way. That’s the one I am looking a motor for. It comes with a motor, but I want to replace it for  one that has a speed controller.
    • Indeed. I would not attempt one. Here is my messy Sherline setup
    • This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.

    • These still seem stupid expensive for a bottle, but still £100 cheaper than than the Moebius ones. Anyone have any experience of these: https://www.cousinsuk.com/product/epilame-fixodrop-special-bottle-horotec
    • Yes, this is not a basic part. Here are some pictures of making one
