I'd also like to know if this works for skydiving. It looks like a nice watch, but I need an alti as well.
ABC (AltimeterBarometerCompass)So, yes, it does.
If you're trusting your life to your wrist bling (ie skydiving) I would probaby choose a skydiving specific altimeter. The altimeter in this watch is meant for gradual climbs, like hiking. Probably not intended rapid-fire, super accurate altitude measurements.
