Actually one of the best features of the apple watch is that it can wake me silently (so as not to wake my spouse) and I can adjust my alarm schedule on my phone (without digging through tiny menus, which are even worse on a Garmin). So I have developed a habit of taking off my apple watch when I sit at my desk. By the first time I think to look at my wrist, it's charged. I put it in sleep mode all night, and wake up with plenty of battery anyway.
