Screen protectors for smartwatches that keep screens clear and fully responsive. Enjoy worry-free workouts and daily wear with a near-invisible, bubble-free finish from LK Apple Watch Screen Protectors. Are the protectors precise and durable enough to stay put during exercise and everyday use?

⚡ At a Glance
  • Touch Sensitivity: Ultra-thin 0.21mm flexible TPU preserves the original touch response and True Touch feel
  • Best for: Active Apple Watch owners who need invisible protection during workouts
  • Not ideal for: Users who want hard tempered glass feel rather than a flexible film

Four clear, flexible TPU films fit 40mm and 41mm Apple Watch series and maintain screen colour fidelity. Self-healing film and bubble-free installation keep watch faces neat while remaining case-friendly.


Responsive touch control - with ultra-thin 0.21mm TPU film

The 0.21mm flexible TPU layer is thin enough to transmit finger pressure and swipe gestures without noticeable lag. The material preserves capacitive sensitivity while sitting directly on the watch glass.

Reliable touchscreen performance for messaging, taps and swipes, including during workouts. No need to lift or reapply protection to regain responsiveness.

True-to-screen clarity - with 99% HD transparent film

Optically transparent TPU delivers 99% clarity and a smooth surface, keeping the screen's saturated colours and contrast intact. The finish reduces visible film artefacts under different lighting.

Watch faces remain bright and legible, so notifications and watch faces display accurately. Ideal for users who rely on readability outdoors or in gyms.

Keeps looking fresh - with self-healing smart film

Smart film technology allows minor scratches to gradually recover as the polymer surface flows to fill shallow abrasions. Small surface marks fade over time rather than remaining permanent.

Small scuffs from daily wear become less visible without replacing the film immediately. The watch maintains a tidy appearance between replacements.
