What these size differences mean
Calculated from the dimensions shown, rounded to 0.1 mm and 1 g. Percentages use the smaller measurement as the reference. Fold and rotation settings affect the dimensions compared.
- HUAWEI WATCH 6 Pro 43mm is 0.3 mm (0.7% relative to OnePlus Watch 3 43mm) wider. Check this difference against the width of your current device and pocket opening.
- HUAWEI WATCH 6 Pro 43mm is 0.3 mm (0.7% relative to OnePlus Watch 3 43mm) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- OnePlus Watch 3 43mm is 0.8 mm (7.8% relative to HUAWEI WATCH 6 Pro 43mm) thicker. Cases and camera protrusions can change the clearance you need.
- OnePlus Watch 3 43mm is 12 g lighter. This is the listed device-weight difference, not a measured comfort rating.
Use these figures to compare physical size. They do not establish one-handed reach, pocket fit, durability or an overall winner.
