Hi all, 

I have recently had the pleasure of working on my first omega, I am at the start of the restoration and am struggling to remove the crystal, is this glued in? The case is a 166.002 with a calibre 565 movement

any tips or help would be much appreciated

So far I have only tried to push the crystal out with my thumbs but even with a good amount of pressure is doesn’t want to move, I did also think this could have a tensioner ring and it’s not something I have encountered before

You should be able to see if it has a tension ring if you look at it from the inside. If it doesn't have a tension ring you should be able to push it out with your thumbs, but as you can't do that I would say it has a tension ring. So, you will need a crystal press to get it out and back in. This could be a good option if you don't have one and are on a budget. I don't have it myself but I'm considering getting one as I'd like a bit more control than I have with my Bergeon 5500 which I demonstrate in this video.

I had a feeling that could be the case I hadn’t worked with one before and tbh the inside of the case needs a good clean so I couldn’t really tell if it had a tension ring, good thing I have the press so I will give that a go later today thank you

166.002

Omega case numbers are interesting because they referred to more of a style of the case then the material it's made out of. Then numbers have also been revised so that your number is actually 166.0020. Then at the link below you can find the casing information I snipped out an image the first one is 18 karat gold with the indication of a ring. The second case that are not snipping out apparently is pink gold and once again it's a ring and the letters are different indicating that the internal ring color would be different.Then I just picked the last one look at stainless steel and once again the letters are different indicating stainless steel ring so your Crystal has a ring which is why you can't easily push it out by hand.

Thank you all for the advice, I used my crystal press and there is a tension ring, the crystal came out whole so I can double check all measurements and get a new one on order, always nice to learn something new in this hobby

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

      By coreymsnow · Posted

      Hi folks, I'm doing some homework on getting a watchmaker's lathe, and it's clear I have a lot to learn. But I know one goal: I want to be able to fabricate wheels, which would require an indexing capability. I know how to use large lathes- like, giant metal lathes- but my experience is a few decades old now (but you never forget the smell of the metal cutting oil). So I'm looking to learn anew, and have a goal to get to a point where I can fabricate some basic watch parts. I also have no specific timeframe and want to do this right, so I'll be patient and learn what I need to before spending the money. I know I'm not going to get anything for a pittance, but I'm also not really able to put together the scratch for a $5-$10k lathe. What's out there for a hobbyist that can either handle some fabrication out of the box or can be relatively easily made to do so? Thanks!

      Hello and welcome to the WRT forum.   This usually points to broken balance pivot.  Though a watch in need of clean & lube can do the same. Easiest diag would be to  see if balance pivot doesn't stay in hole jewel of the setting, when you lift one side of balance rim with an oiler or gently with pair of tweezers. Another would be to detach balance complete from the cock and take a look at pivot under high maginfication.  Regs

      Help with Hermle ships clock

      Ahhh, yes.  I hadn’t thought of that.  I’ve serviced quite a few of these and the first time I didn’t realise it was a ships strike pattern!  Ha ha, confused me totally until I realised.

      Help with Hermle ships clock

      By Rixy · Posted

      Hi Mike, I did, thanks. Found this clip that was really helpful:   It says Seth Thomas but it's actually the same Hermle I've been working on. I'd had it working correctly all along but hadn't noticed that the lever with the sprung end stops the hammer a bit short of the bell on the second ding at the end of the half-past sequence. If only I'd put the bell on when testing, rather than just looking at the hammer, my ears would have told me it was working,  even if my eyes didn't!
