ETEIZU 3-Pack 1.39 Screen Protector for SUNKTA K52 2.5D 9H Tempered Glass

Precision fit for K52 smartwatch

This three-pack of 1.39-inch tempered glass protectors is cut specifically for the SUNKTA K52 military smartwatch and its direct variants. The exact dimensions match the curved 2.5D display edge-to-edge so the touch surface remains fully responsive. Buyers who need a protector for a different watch model or a flat-screen device will find these incompatible.

Simple wet-alignment install

Each pack includes cleaning wipes and dust-removal stickers that let you align the glass before the adhesive grabs, giving a near-automatic bubble-free result. The film lifts cleanly without residue if you need to reposition or replace it. Installers who skip the cleaning step or work in a dusty environment will still trap particles under the glue.

9H hardness with 99.9 % clarity

The 9H-rated glass absorbs impacts and resists scratches from keys, tools or rough surfaces during daily wear. Light transmittance stays at 99.9 % so screen brightness and colour accuracy are unchanged. The thin layer adds no noticeable bulk but will shatter under extreme point pressure, so users expecting unbreakable armour should temper expectations.
