Pocket Watch Crystal Size Chart & Calculator
Watch crystals protect the face of the watch from dirt, dust, and damage. After years of usage, it is common for crystals to become scratched, cracked, or even broken. Replacement crystal sizes are usually measured using the ligne unit system. Measurements are dictated by the case bezel dimensions, not the movement.
Pocket Watch Crystal Size Calculator
Carefully measure the diameter of the damaged crystal or the bezel opening with a micrometer. Enter the measurement below to calculate the nearest ligne size.
Size
Caution and precision should be duly excercised while fitting a replacement crystal, as some may measure slightly smaller or larger than the designated size. Therefore, the figures provided on this page are to be used as a general guide. It is advised to carefully measure the size of the bezel, bezel opening, and crystal to assure a proper fit.
In addition to diameter, the crystal height should also be considered when searching for a replacement. Typically, heights are designated on a scale from 1 to 8. Sizes 6, 7, and 8 are usually best for hunting cases.
