Since someone pulled up this necro-thread anyway, I'll ask a question.

Is these any particular reason why neither watchmaker opted to use a crystal puller?

Pullers are useless for sapphire, but should work on haselite just fine. In fact, I have used the to compress and drop in new acrylic Crystal's when I didn't have the right press die. Is this an option given geometry of the bezel? I've never had a speedmaster apart.

Thanks.

The claw style crystal removers are not meant to be used on acrylic crystals that have tension rings - they are only for crystals that don't use tensions rings.



There are a few very brand and watch specific specialized versions that do work with tension rings, but a different tool is required for each size, and they don't use a multitude of claws, but larger segments (Omega's tool 107 for example).

The whole time I'm reading @ashleysteadman's post, I'm on the edge of my seat holding my breath thinking, "Oh man ... what @Archer have to say about all this ...," and then all of a sudden ...!

If you look very closely, you can see the Omega symbol here on the new crystal (picture taken through loupe):

Thanks for reading! Hope this is helpful 😀

And Ashley,
Would this same technique work for a mark III 176.002 crystal?

Truth of the matter is that, there is much input on what anyone would have done, instead of actually doing it as the original author did. I personally followed each step and successfully replaced my crystal. So, many thanks for the initiative and willing to help others. Cheers!

Hi all, I'd like to revive this thread with a follow-up question. Which sizes of dies would you recommend to push out and then press in a crystal from either the straight lug (pre-professional) and for the lyre lug Speedy? I have both cases and would like to service them, so I'm looking to buy the minimum number of dies needed. I do not plan to service any other watch than my Speedies. Thanks!

You plan to just service your speedy? Have you serviced anything else?

I’ve always just picked out a correct fitting die from the standard die assortment. Didn’t realize they sell them individually.

Yes, I plan to service just my speedies and nothing else.

You can either buy a full set, or select individualy. As I don't plan to service more than my two types of cases, it is not worth for me to own the full set.

Well, best wishes. However, fair warning—I’ve been servicing my own watches for close to five years, have thousands in tools, and I’m still not quite comfortable servicing a speedmaster. There is a significant learning curve and you will need to spend a lot of money on tools and mistakes to get half decent results.

Thanks but do you know the sizes of dies that I asked for in the first place?
