At Chaperon, we're constantly working behind the scenes to improve and optimize. A key part of this is adding the crystal sizes for vintage and recently released watches. It appears the crystal protector isn't yet linked to your watch. We'll work with you to resolve this, so your watch crystal will be protected soon.

For round watch crystales: Use a (digital) caliper to measure the part of the watch crystal that needs to be protected, this is the flat part.

Please note: If you have a round crystal with a Cyclops (magnifying crystal), a rectangular crystal, or another shape, please complete the form below and we will look into the possibilities.
