Installation Advise

For the best results from swapping the watch crystal, do take not of the following points:

  • The flat sapphire crystal replacement is to be done by your own watchmaker.
  • A new crystal gasket will be provided.
  • Ensure that the correct size of feet on the case-back removal tool are used to prevent scratching the case.
  • Ensure that the seconds hand post is fully pressed down to maximize the clearance distance between the seconds hand and the flat sapphire crystal. Once ensured, there will be a 0.45mm clearance distance.
  • We highly recommend a waterproof test to be done after the installation to ensure the watch's 200m water resistance rating.
