When Casio introduced PRO TREK with offline maps, it was a god sent for trekkers, but it is lacking one key feature modern active wearables has: heart rate monitor.

It comes equipped with a lithium-ion battery that offers around a day and half of use without GPS, or up to 20 hours with GPS. However, it could run for about a month of it is on timekeeping and sensors only mode, and it is, of course, powered by Wear OS.
