Choosing the Right Crystal
The crystal protects the dial while also contributing to the overall appearance of the finished watch. Different materials offer different characteristics.
Sapphire Crystal
Sapphire crystal is a popular choice for builders looking for a more premium feel and strong scratch resistance.
However, don't simply search for a crystal based on diameter. The crystal needs to be compatible with the specific case and mounting system.
Check the measurements
Before purchasing, check the listed diameter, thickness and crystal profile. If the case requires a particular gasket or installation method, that should also be considered.
Bezel Inserts
A bezel insert can be one of the easiest ways to change the visual identity of a diver-style watch.
Popular designs include traditional dive scales, GMT-style markings, different colours and ceramic-style finishes.
The important thing is to confirm that the insert matches the diameter and shape of the bezel on your case.

One of the biggest mistakes beginners can make is buying a crystal before checking the case specification.
Different cases can require different crystal dimensions, profiles and fitting methods. Always use the case manufacturer's measurements where available.
