Watch Fit 4 — Frequently Asked Questions
Will the Huawei Watch Fit 4 fit my wrist?

What size band does the Huawei Watch Fit 4 take?
20mm. Any 20mm strap fits, so you are not limited to Huawei's own bands — look for a quick-release fitting if you want to swap without tools.
How long does the Huawei Watch Fit 4 battery last?

How does the Huawei Watch Fit 4 battery compare with other Huawei watches?
At 10 days in everyday use it ranks #20 of the 61 Huawei watches in our database — the top 33% of the range. The full ranking, including GPS and power-saving figures, is on our Huawei battery life comparison.
Is the Huawei Watch Fit 4 thick for a 38mm watch?
At 9.5mm, thinner than 78% of 38mm watches, so it slides under a cuff more easily than most of its size. Thickness, not case width, is what decides whether a watch catches on a shirt cuff.
What other watches are the same size as the Huawei Watch Fit 4?
Apple Watch SE 3 - GPS + Cellular · 44mm, Certina DS Action Diver 38 Powermatic 80 PVD / Black, Omega Railmaster Omega Co-Axial Master Chronometer 38 Stainless Steel / Grey Gradient, TAG Heuer Formula 1 Solargraph 38 Black Polylight / Black / Rubber all sit within half a millimetre of the Huawei Watch Fit 4's 38mm case, so they cover the same amount of wrist.
What is the lug-to-lug of the Huawei Watch Fit 4?
43mm, against a 38mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
