Glass question

[Danh]

I will try and make this brief.

someone in my town posted on Facebook that they were selling their dads watch making equipment. I jumped on it to have a look. Turned out their Dad has passed on and they are selling everything for a child's hospice in Scotland.

there was a load of stuff, I was in heaven. I bought what I could afford and advised a bit on some of the more expensive stuff.

some of my purchases included glass / crystal removal and replacement equipment.

my M Lacroix needs a new glass as it is looking imperfect around the edges (it is 20 years old)

i am not sure wether to lift it out or press it out. To be honest I do not know what the glass is made of.

would anyone be kind enough to give an opinion please, it would be most appreciated .

it also begs the question about whether a glass would be obtainable from the likes of cousins also?

Is it flat or domed?

It is domed 

[oldhippy]

If you have one of these you can remove the glass. I expect as its domed it is plastic or a type of, I wouldn't think its glass. In my days there were two types of domed low and high. There is a link somewhere with video on this forum that I put up from youtube showing you how to measure for a new glass. If you don't have a tool for removing take the movement out and just push it. But you will need this to put it back or at least watch glass fitting and removal tools.

That's brilliant thanks, that is one of the pieces of equipment I purchased, the other piece was a press

most appreciated

Some times with the tool that is pictured low dome glasses can be a bit hard to pick up. The tool I had was like in the picture an expensive type not one of these cheep Chinese things you can pick up for £10 on ebay

The one I got from the watch maker was Bergeon

That will do it.

So will the cheap Chinese one.

I would always take the movement out if changing the glass.  Gives a chance to give the case a good clean with soapy water and a toothbrush.

This one looks like it might be a sapphire crystal with a ring seal. With the movement out a plastic glass will normally push out with thumb pressure. Omega has a video on their website showing a sapphire crystal being removed with a hammer

Given that the crystal has nibbles at the edge, I agree with you Stuart.

A press and dies will be the order of the day for fitting a new crystal.

Great thanks guys, I got a press with a ton of dies with all the stuff I got

I wouldn't know. I've heard about these cheep Chinese tools and never had any I could only comment on the type that I had and used. I also asked what type of glass it was as I couldn't tell from that photo.
