Acrylic crystal replacement
I used to own 2 GMT Masters, sold a 1981 ref 16750 for next to nothing and also Tudor Military Sub.
I was rummaging through my watch stuff and noticed I have a few acrylic crystals that have been replaced. Two of them didn't even seem like there was anything wrong with them. I did have both GMT Masters and the Tudor Military Sub serviced so I was wondering if the acrylic crystal and rubber gasket are replaced each time the watch is serviced? |

Yes, as far as I know and in my experience. However if you are in the USA, you usually don't get the replaced parts back. I also still have the original top hat acrylic from my 1680 that was replaced a couple of years ago.

Thanks for the reply. I imagine it has to do with keeping it waterproof. I'm having a 16013 being serviced and the watchmaker told me the crystal also has to be replaced. Not sure if it's an acrylic or not.
The GMT Masters were serviced through an independent watchmaker although the Tudor Sub was serviced by RSC New York. |

Visually an old acrylic crystal may appear fine. But over time oxidation, UV and even gamma rays cause molecular level changes that weaken the crystal such that it becomes less compliant and prone to cracking.
The gaskets also lose their sealing properties and can crack. So hey, too are replaced as insurance for water resistance.
