Smartwatch Screen Protectors

Tempered glass and screen protection for Apple Watch, organised the way you actually shop — by case size. Check the number on the back of your watch (38mm, 40mm, 41mm, 42mm, 44mm or 45mm) and pick the matching protector: every Apple Watch generation that shares your case size takes the same protector, from Series 0 through Series 11 and every SE. Catalyst screen protectors are precision-cut for each size, fit flush with curved edges, and keep full touch and sensor accuracy — so scratches, knocks and drops reach the glass we make, not the screen you paid for. Pair yours with a Catalyst impact or waterproof case for complete protection.
