Gaskets A Go-Go

So my watch collection runs to a store-brand divers - but with a brevet case and an old, but good ETA 536-121 quartz movement, a Swatch with a 5-jewel Ronda 705 ($300 bucks for. $20 movement - sheesh), my Seiko 5106 - currently on the hoist for a clean, and store-brand pocket watch, and a family heirloom, which is currently off limits. Photos to follow...

I serviced the divers myself, and the Swatch, but I'm having a heck of a time finding gaskets, especially the crown and stem gaskets. I've only looked at Ofrei, Esslinger and CousinUK, but maybe I don't know how to spec the gaskets. My divers crown gasket was too damaged to measure, so I measured the tube OD, the crown ID, did the math and a 3mm with a 0.5mm thickness should have done it. So I bought that size and the next size up.

0.5 was too thin - although I'm using it for some protection - but the 0.7mm thickness was really tight going into the crown, even well lubed with silicon grease. And there was no 0.6mm.

And now I'm looking at that tiny stem gasket on the Seiko, and the case back and wondering how to spec that thing...I saw a previous post about Boley, so I'm headed there next, but advice on measuring techniques, fitting up and sources would be very much appreciated.

      My overall preference is to use traditional names and terms, that became my habit when i was taught joinery by old boy chippies 2 generations older than me , that had their time in the 40's. But what i often do is adjust the names and terms i use according to who I'm talking with. Sometimes i will say trainside and occasionally watchmaker's side. I try to find a balance between accommodating other folk ( there's no point speaking a foreign language to someone who doesn't understand it ) and using a name that appears to me to be more relevant as to its use or description. But using the name lever can be quite confusing,  some watches might have parts that are also levers, release levers, which in effect is what the pallet fork is, an escapement release lever.

      Need Advice for Armoured Crystal

      I come across to replace the crystal of a 7734 chronograph.  What make it special there a printed chapter ring  which fits inside the recess of crystal before inserting into the case. I am thinking of a high dome crystal such as Sternkreuz ATCH, fitting diameter OD332/ID320.  For this purpose, tension ring will be removed and fit in the chapter ring.  I understand the crystal size may not perfectly fit these two dimension.  Should aim to find the right ID, then OD can be grinded to reduce without much difficulty.  To find the right crystal, the easiest way is to get know of the OD/ID relationship of Sternkreuz ATCH/ATCG (otherwise the OD of the crystal and tension ring).  I hope you are able to help to minimize the trial and errors.

      The case number should be on the back.

      I agree, I call it a pallet fork for two reasons, it was the name used when I started watch repair both in written documents and on videos and calling it a lever causes confusion as seen.  Plenty of other examples where there's more than one name. What do you call the opposite side of the movement from the dial side?  I've heard you call it the watch makers side.
