Watch Ultra 3 vs Pixel Watch 3 (45mm)
A side-by-side readout for weight.
Understanding weight
Weight is a numeric spec measured in g. On this metric, lower values are generally better — smaller, lighter, thinner, or less demanding usually translates to a more comfortable or more efficient product. When comparing two products, focus on the percentage gap rather than the raw delta: a 200-unit lead means something very different at the low end of the range than at the high end. Pay attention to the unit, too — manufacturers sometimes quote peak or burst figures that are not sustained in real-world use. Cross-check the published number against independent measurements where possible, especially for performance and battery claims. Finally, remember that a single spec rarely tells the whole story; the Mars Score weighs weight together with the rest of the spec sheet so one outlier doesn't distort the verdict.
This matchupWatch Ultra 3's 62g is roughly 68% more than Pixel Watch 3 (45mm)'s 37g (a 25g gap). Lower is better here, so Pixel Watch 3 (45mm) takes the lead in real use.
