TicWatch Pro (I do not own it) has a 2nd layer screen that uses very little power and can last many days. However the watch is too big for my taste, but always on is a must. I purchased a refurbished Samsung Galaxy 42mm. I can last well into 1.5 days without charging (it usually gets topped off). The newer Samsungs can barely last a day.
