SWC Video Tutorial: Installing our sapphire caseback using a plastic screw ball
April 16th, 2010
Here is a video of the installation of our sapphire caseback on a Rolex GMT-Master using a plastic screw ball. The installation is very easy and works well. We even put the watch in a water resistance testing machine, set at 0.5 and 3 bars, to prove that the caseback, when installed properly, does not affect your watch’s water resistance.
If you are planing on using your watch in the water after installing the caseback, please remember to get it tested for water resistance before to make sure it has been installed properly.
