Key differences
The most meaningful measured gaps in size and weight — not an overall winner.

Weight
Very similar weight
Height, width, thickness, and weight are very similar between these devices.
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.
- Google Pixel Watch 5 45mm is 0.3 mm (0.7% relative to Vantage M3) wider. Check this difference against the width of your current device and pocket opening.
- Google Pixel Watch 5 45mm is 0.3 mm (0.7% relative to Vantage M3) taller. This describes the body outline; screen diagonal alone does not tell you the overall size.
- Google Pixel Watch 5 45mm is 0.1 mm (0.8% relative to Vantage M3) thicker. Cases and camera protrusions can change the clearance you need.
- Vantage M3 is 2 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.
Sources and measurement notes
Sizometry compares published specifications and calculates differences. These are not hands-on measurements or tests of comfort, performance or pocket fit.

Folded and unfolded dimensions differ; cases and camera protrusions may change the space a device needs. Drawings share a relative scale and are not calibrated to life size on your screen.
