OK guys, I have swapped many a replacement acrylic crystal, but never a mineral / sapphire glass crystal.
Specifically, I want to swap a flat sapphire crystal with cyclops from a submariner, for a domed no date type to change a run of the mill sub into a Tudor no-date sub. I don't know quite what to expect during removal/replacement.
Firstly what is the best way to remove it?
Secondly, installation. I have heard that you need a crystal press, and that there may be a gasket between case and crystal. Some crystals, I believe, have a tension ring??
The sub came from Trusty and is the old ETA version from 3 years or so ago, if that makes any difference.
All help greatly received.
