Shows a high reliability in its measurements. Altimeter: Although initially calibrated on a day I deviations of +/- 20m which is exceptional. Barometer: again, very reliable! The watch is able to switch between the single and baro violas without the deviations are felt only! Depth: tested up to 15m with a diver equipped with a pro Depth: no difference!
The only downside is the compass that at times seems completely derail!
I have this watch for two years. She did not leave me and I do not intend to change!
