This version of Ten Hands has a 12 hr hand for people who have a hard time reading a 24 hr hour hand, where a 24 hr 2 Oclock looks like 12 hr 1 Oclock, etc. World time hands are 12 hr now. A yellow marker tracks 24 hrs. Chronograph has hundredths and seconds in red digits. Set your time zones in Watchmaker settings, and location text wil change. Upper orange arc shows sunrise and sunset and day length, lower blue arc shows night length. Edited for better readability. Tap center of dial to launch heart rate. I discovered a constantly running HR will drain the battery too fast. Battery guage has orange hand for watch, green hand for phone.
