Hi Everyone,
I was recently given a Wyler Vetta (ETA 32) watch with a stuffed movement and ratty case + crystal.
I've since serviced it and de-rusted it, waiting on some lume for the hands, cleaned up the case.

The man who gave it to me is dying from cancer, and it means a lot to me to fix it as he is like a grandfather to me (I'm only 25 in this hobby).


My dillemma is the crystal!

I've ordered a 32mm GHD crystal for $30 with postage and it turned out to be to small on the inner edge but too large on the outer.
Can anyone advise based off the measurements?

The inner diameter of the crystal was 30.6mm
Outer diameter is 31.85mm or so.

The inner bezel ring sits just on the dial, so that makes no difference.

The tension ring inner diameter is approximately 31.9
The crystal I got was from tiptopcrystals:
https://www.ebay.com.au/itm/G-S-XHD-EXTRA-HI-DOME-18-35-24-1mm-35-2mm-Round-Extra-High-Dome-Watch-Crystal/191801252753?ssPageName=STRK%3AMEBIDX%3AIT&var=490828457029&_trksid=p2060353.m2749.l2649

It was the 32mm GS XHD 30.1/2
Should I go for a slighly larger from same seller or ATG Sternkreuz from cousins? Can anyone suggest sizes.

I tried milling down the tip top crystal with a scalpel however ended up wrecking both he sent me.

you need the   proper wyler crtstal.     they may not be available.   try to find a watchmaker [or a forum member] who has the right one.     it can be chucked in a lathe to cut the edge inner dia. for the ring + clearence.  vin

You're not alone in having issues with fitting crystals. I guess that's why jewelers/watchmakers generally have a good assortment to chose from. I've had good luck most of the time by measuring many times to be sure, but I did recently buy the wrong size and type for a forties Perregaux. Going trial-and-error can be costly with $30 crystals. You might consider sending it to a specialty crystal replacement service if you can't find the Wyler product.

BTW: If you find the Wyler crystal, you might try to get two. :-)

Oh, and vinn3, that's interesting about the lathe use for adjusting the edge thickness. Would you use a bezel-chuck?  I ask because that happens to be one that I have. Thanks.

The type of crystal you need is one that sits on top of the rehuat and is held in place by the bezel , like the Rolex Oyster .

The Sternkreuz crystal for this type of fitment is the ST or XS type , but unfortunately i can't see one in the sizes you mention.

Have you measured the external diameter of the rehuat and the inner diameter of the bezel ?

I have a selection of aftermarket crystals - all high dome.  I have a plastic 4 jaw chuck to turn them.  Wyler is a problem,  also Ernest Borel.   these are among the VINTAGE  watches that need a factory crystal.  I think they all are in private hands.  vin

Gotcha. That's too bad. I hope that one turns up. Good luck.

And thanks for the clarification on the type of lathe tool you used for the crystal adjusting. I've never seen a plastic 4-jaw. Granted, I don't have much experience such things. Cheers.

its just like a steel 4 jaw,  but its a bit loose and flexible.  when I find it, ill post it.  vin

Thanks, vinn3. Yes, I do know what a 4-jaw chuck is. I have a 3-jaw for a Unimat lathe that I've had for a while. I believe the 4-jaw is the same, but with 4 jaws that allow for more precise centering. I got the 3-jaw because it's a bit easier to use for the newbie.

A plastic 4-jaw does sound like a good way to go for adjusting crystal thickness at the seat. I'll keep my eye out for an image. Thanks again. Cheers.

Perhaps the 4-jaw is better than the 3-jaw because you can center non-round work as well?

 

right you are.   a new uniat lathe would come with both chucks.  its a 1/2 x 24 thread i believe.  a used unimat may have a drill chuck.   i am using a 6 " lathe.   it takes years to master the 4 jaw.   a 3 is darned fine if you are cutting larger stock.   the hunt goes on for my plastic 4 jaw.  vin

If anyone is interested, I found the original crystal 2 years ago on ebay. I found it by searching the dimensions and brand name "wyler".
I also got the dial refinished last week, looks a lot better.
The font is gone, but the memory is forever.
My good friend died shortly after I found the crystal, but I will keep the watch hopefully forever.

      A lathe with indexing that won't break the bank?

      By JohnR725 · Posted

      interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.

      Lab Coats

      Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything.

      Chinese tools debate

      By Titanium · Posted

      Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.

      I found this string about this problem. I've not gone through it all, but I believe it also mentions making a spring. If not in this string, the info is online.
