Choose between tempered glass or flexible PET film based on your needs. Glass offers high hardness and scratch resistance, while film can be self-healing and more flexible.

Edge Coverage
Full coverage protectors protect the entire screen and edges. This helps prevent dust from getting under the edges and causing damage.

Touch Sensitivity
A good protector should not introduce lag. Look for thin designs that maintain the original responsiveness of the display for smooth navigation.

Water Resistance
Verify that the protector does not interfere with the watch IP68 rating. Strong adhesives are necessary to keep the protector sealed during water exposure.
