Piuellia Apple Watch 40mm Case, watch protection for Apple Watch 40mm that uses ultra-thin, crystal-clear TPU to guard against scratches and everyday bumps. Keeps a clean, polished look so owners can wear the watch confidently at work or during casual outings. Will clarity and low profile make it the better choice over leaving the watch bare?

⚡ At a Glance
  • Protection Level: Slim TPU full-body cover resists scratches and daily knocks while preserving touch access
  • Best for: Apple Watch 40mm owners who want near-invisible protection without extra bulk
  • Not ideal for: Wearers who expect a waterproof seal during heavy sweating or intense exercise

Full-body TPU cover for Apple Watch 40mm that preserves screen responsiveness and high transparency. Non-adhesive design may trap moisture during strenuous activities, so caution is advised for gym use.


Clear, low-profile protection - with premium TPU construction

Smooth, high-transparency TPU wraps around the external surface to shield against abrasions while remaining thin. The material maintains optical clarity so the screen remains easy to read.

Original watch aesthetics remain visible while edges and screen gain reliable scratch resistance for everyday wear.

Unobstructed touchscreen responsiveness - thanks to ultra-thin design

An ultra-thin cover layer transmits touch inputs because the flexible TPU sits close to the glass without introducing rigid gaps. Touch sensitivity stays intact as the material does not interfere with taps and swipes.

Navigation, notifications and quick interactions work as expected, avoiding the fiddliness that thicker protectors can cause.

Accurate access to controls - with precision cutouts

Careful moulding leaves clean openings for the crown and side button while covering exposed surfaces, so controls remain reachable. Edges are shaped to match the 40mm case footprint.

Easy to fit and use, with normal access to controls and no need to remove the cover for everyday tasks.
