No. Cellular isn’t required. The watch GPS is not dependent on cellular network to work.

The Apple Watch doesn't measure VO2 Max, it estimate it. The Apple Watch doesn't need internet access to estimate VO2 Max, it only need a good GPS signal.

VO2 on Apple Watch is a joke

[–] redavid@alien.top 1 points 10 months ago

it doesn't measure vo2max at all. it does need GPS data for an eligible activity (>20 minute outdoor runs/walks/hikes) because the estimate it'll spit out is reliant on some data like distance, pace and elevation that is derived from GPS (and other data points, namely heart-rate). none of that stuff requires a data connection
