Measure the size of the glass protector

  • Option 1


    Measuring with a caliper

    For round watch crystals: Use a (digital) caliper to measure the part of the watch crystal that needs protecting; this is the flat part.

  • Option 2


    Measure with a measuring tape

    For round watch crystals: Place the measuring tape on the watch crystal at the 9 and 3 o'clock positions. Measure the part of the watch crystal to be protected there; this is the flat part.
