There is Amazfit Pace on the low spectrum of price and Garmin on the higher end. All with transflective screens and battery that varies from 4 to 10 days, depending if you want to receive notifications on your watch (and how many, Slack for example is pretty heavy due to the number of notifications).

I own a Pace and I am pretty happy with it. Not a complete smartwatch but has all the important features for me: always on screen, stylish, acceptable battery, activity tracking and notifications.
