Two-Tone TPU Case for 40mm Series 4

This Nakedcellphone case wraps the 40mm Apple Watch Series 4 in flexible TPU rubber. A two-tone black and yellow design adds a sporty look while precise cutouts keep the crown, sensors and touchscreen fully accessible. The elevated lip recesses the screen to guard against direct impact. Lightweight material resists corrosion, dents and tearing while returning to its original shape after stretching.

Owners wanting bumper protection without bulk

The open-bottom design prevents wrist chafe and allows wireless charging to work normally. Buyers who want full-screen coverage or a built-in screen protector should look elsewhere. Anyone needing a ruggedised housing rated for water immersion or military drop standards will not find those certifications here. The case suits daily knocks and scrapes rather than extreme environments.

Handles everyday bumps and scrapes

Flexible TPU absorbs shocks from accidental impacts on counters, doorframes or gym equipment. The raised bezel protects the display when the watch rests face-down. Material stays intact through repeated flexing but is not armoured against crushing forces or deep abrasion. Protection covers the perimeter only, leaving the underside exposed for sensor contact and charging.

Questions about this item

Do I need an Apple Watch Series 4 in the 40mm size for this case to fit?

Yes, the case is made specifically for the 40mm Apple Watch Series 4 and will not fit other models or sizes.

Will the case interfere with the Digital Crown, sensors or touchscreen on my Series 4 watch?

Precise cutouts keep the crown, sensors and touchscreen fully accessible while the case is installed.

How can I confirm the case is seated correctly after I wrap it on?

The flexible TPU rubber should snap back to its original shape with the elevated lip sitting evenly around the screen and all cutouts aligned.
