Skip flat glass. The Pixel Watch's cover glass is domed, so rigid flat protectors touch only the middle and lift at the edges. Use a full-cover TPU film that wraps the curve, or a bumper case with a built-in cover, matched to your case size: 41 mm or 45 mm.

Case size is the number to match, and it's the number on the listing. Generations with the same size often share protectors, but the dome's exact curve can change, so prefer a product that names your model.
Why the dome matters
Most watch protectors are made for flat or gently curved faces. The Pixel Watch's glass rises noticeably towards the centre, so a flat sheet bridges the middle and leaves a visible gap and a lifting edge around the rim. Three things work instead:
| Option | Fit | Trade-off |
|---|---|---|
| Full-cover TPU film | Follows the dome | Scratches only; can look slightly soft |
| Bumper case with integrated cover | Protects rim and face | Adds bulk; best for knocks |
| Nothing | — | Reasonable: the dome means most contact is glass-on-nothing |
Door frames beat scratches
On a domed watch, the glass sticks out further than the case, so impacts land on it first. That makes a bumper the more useful purchase for most owners: it raises a lip above the dome so a door frame or dumbbell hits the bumper instead. A film underneath handles scuffs from sleeves and desks.
Questions people ask
Can you put tempered glass on a Pixel Watch?
Flat glass fits badly because the cover glass is domed. Full-cover TPU film or a bumper with an integrated cover works better.
What size is my Pixel Watch?
Recent models come in 41 mm and 45 mm; the original and Watch 2 are 41 mm only. The size is on the watch and in the companion app.
