This is a really nice watch. Thin and comfortable. Elegant yet discrete. Sadly the software limits it to a very coarse monitoring of just trice an hour(!!!) - I hope they will give us more uptions in a software-update. The positive side of the coarse monitoring is that it seems to have a stamina of over 3 weeks! That is far from common in such a compact body. I wrote a review of it here https://eskerahn.dk/?p=7268 Note that it is the clear winner of a test i did on detecting sleep too.
