Tutorial: How to fix the Bezel on a CLEAN GMT Master 2

[TonyMonatana44]

That product looks like it's from the UK and cannot be purchased in the US. You can order it from Amazon but shipping comes out to more than the bottle and a 2-3 wait time period.

I've used dielectric grease in the past and it worked wonders (the same grease you put on spark plug boots in your car). I know it's not a "lubricant grease" but i've found it to work wonders with water and stays greased for a long time, even when swimming with the watch in the Adriatic sea water.

If you don't want to go that route, you can always use metal specific lubricating grease such as: https://www.esslinger.com/molykote-...Q-1FCoOzyG-O7WfVPTQsOhoIBT3fOoPEaAkLyEALw_wcB

That stuff works great too.

What kind of grease should be use to put onto the teeth of the crystal retaining ring?
Should those for the bicycle chains be OK?

Nope. That shit sticks. Silicone grease for watchmakers on aliexpress is what i used

Pretty sure any silicone grease will do.

Thanks for all the advices. I have on hand the Moebius 9415 grease, should it be good enough for the job?

BTW, how to remove the crystal retaining ring on the GMT? Use the razor blade as that for the Subs, or just press out the crystal will work?

Sometimes everything (retaining ring, crystal gasket, and crystal) will all come out at the same time when removing the bezel. Sometimes it'll all come off at the same time when removing the retaining ring.

If it doesn't come off, use a utility knife or razor blade with a hammer to wedge it under the retaining ring and gently and evenly pry up 4/5 sides working it up. You will want to tape up the watch case with tape or sticky notes or something to protect it from getting scratched up.

Just keep in mind that the retaining rings are sometimes super tight and they require a lot of force and or time to get lose.

Im going to use the razor blade and hammer technique to get a gap and then one of those 4 jaw bezel removers to lift it evenly. Taping the case up first

6 fresh crystals have arrived from Prof. Still awaiting the bezel remover

You can do it without the bezel remover. I just removed my old GMT Master II Pepsi retaining ring last night with a razor blade. It was super tight but if you evenly lift it up on 4/5 sides of the case it should pop out after 2 minutes.
