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 .

Maurice Lacroix Masterpiece Reveil

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

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.

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 :startle:

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.

So will the cheap Chinese one. ;)

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.

      Breitling Navi Heritage (ETA 2892A2) seconds subdial skimpiness...

      By JeremyLaurenson · Posted

      I thought this may be "right" forum to post this. After 7 months out in Switzerland I got my Navitimer back from Breitling. I had sent it off since its 20 years old to have a complete overhaul done... Nothing major wrong, but I did notice this seconds sundial skipping thingy.... $1300 later and 7 months later, I notice the 'skips' are still here unless the chronometer is engaged. I would think this is likely the hand binding up and maybe clearance with the dial, but at any rate Im interested as to whether this is something I should be returning the watch to Breitling for and insisting on being fixed. See below - 1 minute or so of regular running and then 1 minute with the chronograph engaged.

      How to recognize radioactive watches.

      By WatchesFarm · Posted

      Hello everyone, I recently received a request for advice on purchasing a vintage watch, a Waltham A-11 ORD. DEPT. I asked if they were aware that these types of watches have radioactive hands and dials... but they had no idea what I was talking about. So, I thought of creating a video that could help recognize them, starting from the distinctive details to using a Geiger counter. I hope you like it and find it useful for those venturing into the world of vintage watches. Bye.

      Chinese clone demagnetizers

      I’ve tried everything using both my blue and donut demag units.  I’ve even tried beating them with a steel hammer 🙂   im now trying heating them over gas flame — if that doesn’t work …..

      The 110v supply could be problem with the blue one. Have you tried moving the piece to demag through different orientations manually as its drawn away ? As Nev quoted the magnetic fields of the demag have to overcome those of the steel.

      Thank you Marc! I re ran the TG. First I went ahead and checked the balance jewel on the regulator and it was bone dry. I cleaned and oiled it, not without some drama including pinging the capstone and searching my bench with a black light for 30 minutes and finally shone it on my face and looked in the mirror only to find it on my left cheek in my 2 day growth! Back in and on the Grapher we are at 275. However significant drop in DD (234) and CR (190 edited) positions tells me it's time for a complete cleaning and oiling.
