This will be my first crystal replacement, I have a press, but looking at the watch I wonder if I might need a bezel tool also. Any and all help appreciated.

Tool for removing or pressing the bezel? Most likely you have to remove the bezel (with a knife) before removing old crystal or inserting a new one. You can press the bezel with the crystal press if you have a suitable die with straight walls or otherwise a die that has enough clearance that it doesn't touch the crystal when pressing the bezel.

It's difficult to tell, but my guess is it just looks like it has a bezel. Once you have removed the movement, you should be able to tell. Either way, I think you should be able to press out the old crystal from the inside as long as you have a die that properly supports the bezel around the crystal. So, take it apart first and then assess if any additional tools or actions are needed. Let us know how you do!

From what I see, the crystal is made of mineral glass and is secured to the bezel with a sealing ring.

If you might want to replace the crystal without removing the bezel or the movement, I think it's possible, but risky. You have to suck out the old crystal without breaking it into tiny particles. I would not do that.

If you remove the movement first you can press the crystal out and press a new one in without removing the bezel.

Well, turns out it was a fake bezel! The crystal is domed mineral glass and I was able to find a cheap replacement that should be here in two days. 

I used my crappy little press to pop out the cracked crystal, Ill give the case a good cleaning in the meantime and do a once over on the movement.

Double checked, definitely a fake bezel. It has a thin plastic gasket that creates the seal for the crystal. I went ahead and gave the case a good cleaning, and light polish. Now Im just hoping I can install the new crystal with out screwing up! I will likely be putting it in tomorrow night.

It can be a good idea to replace the gasket as well, especially if has any kind of damage. If it's a very tight fit between the gasket and the crystal, a thin layer of silicon grease on the gasket can help a lot. Keep us updated!

For me a fake bezel looks like a bezel but is part of the case. I understand what you mean though.

First major fail. Finally got in my replacement crystal. Ordered 31.5mm x 1.1mm double domed mineral glass. But it didnt snap in. Tried adjusting but I was able to pop it out by hand easily. Tried again and again until I shattered the crystal. With the gasket in the case the inner diameter is 31.5mm, with out the gasket the case inner diameter measures 32mm. What size should I go with?

Normally I-Rings for around 1mm Crystals are either **.2 or **.7 to match with **.5 & **.0 crystals.

i.e. a 32.2mm I-Ring would be a 31.5mm Crystal.

Based on your measurements I'd have thought the 31.5mm would be correct.

Where did you get it and did you measure it?

Edit

Just looking at your photos.

Was it a double dome 1.1mm originally as the I-Ring looks very deep for that size?

Got it off amazon, brand is Harfington. I just measured and it measured at 31.37mm diameter and 1.01mm thick. The original measured at 1.22mm thick. Maybe I should have ordered from esslinger. Gonna fix that now.

Checking ID with the old gasket still in place is useless. Remove the old gasket, using a good quality caliper check ID - this is your new Gasket diameter. New gasket should fit just right in the bezel. It should not be moving at all, but you should not apply any force to put in place.

Assuming that I - Gasket Thickness is 0.35mm, Glass & Gasket Ø32.00mm the Glass diameter will be 31.30mm (31.30 + 0.35 + 0.35mm = Ø32.00mm)

You need to get a 1.2mm thick crystal, or possibly a 1.3mm.

    • I said it was a learning effort...I learned a TON!!! It was a great learning effort. Your time was much appreciated and led to a much deeper understanding on my part of many many things. I'm sorry if what I said gave a different impression. When I said it didn't work out, I meant in the sense that I wasn't able to repair the problem on the pocket watch I'm trying to service! More later... 😁
    • Here are the photos of the mystery watch. Grateful for any help with identifying it. Thanks everyone. Your knowledge is invaluable 
    • Checked already it is 1.9mm. Meanwhile I came also to the same conclusion that the MS I am looking for is numbered as 2230 which is 2.05 mm in height (and made in different strengths), that's the reason why I double checked.. maybe it is the correct height. The barrel lid is actually not the press in type but the one which sits on the top so maybe the 2.05 what we are looking for. I put the barrel arbor and lid together and I think the gap and the 1.9mm adds together to 2.05mm:   2230 here which is for size 0s & 3/0s:  https://pocketwatchdatabase.com/reference/mainsprings  
    • That would actually be very clever and it would probably wash off the lubrication. You're supposed to apply it to clean parts then let it run a little bit and then apply the lubrication. Software-based timing solutions is a interesting term because you do require some hardware. As the world of timing machines have gotten more complicated even things like which he timing machines that might appear to be a physical timing machine are not they're basically a PC running well the machine at work is running Windows CE. Which from time to time has to be rebooted because it decides it doesn't want to work. Currently witschi decided that probably the intelligent move that they really not in the manufacturing and now they microphones with USB typically so expensive microphone because they have all sorts of nifty electronics buried in the thing and software in use apply the PC. Then as this image was convenient here's an example of what I was talking about how other methods of showing things can show things.This image was convenient I have others that are way more dramatic but you can see the effect of the gear train having some power fluctuations not bad though for 17 size vintage Elgin watch. In any case you can see the effect of the power and the gear train producing Uneven power and yes all gear trains are going to do this to a certain degree it's just the way they work and then we can see the output changes a little bit but not enough to be really concerned about for watch like this. Then the lift angle is probably not correct for this particular watch either So basically for any software you get your going to need a microphone and that will require some electronics fortunately some other people making software grasp this and they will supply a microphone.   Here's a program that I've used. This is their US websites I do find websites for timing machine software or even timing machines quite interesting because apparently whoever comes here is supposed to grasp everything about whatever it is there purchasing where typically they may not especially if the software has enhanced features. https://www.etimer.net/ Then we have PCTM As you see highly recommended by others on the group. I think you going to need the enhanced version which you have to pay for I only have the free version. Frank's website is a bit hard to find and does seem to lack pretty pictures and descriptions of how the software works although he does of a PDF that explains this if you could find his website that is.    
    • So are you saying the existing spring is 1.65mm high? If that's the case then it's the wrong spring to start with. You also need to check the barrel depth again to confirm this is correct.
