Fun with WM Red in the dark but was worth it. 12 months of the year but highlighted in red indicator when its in current month. Date features day of the week, day & year with built in Wi-Fi, step counter, moon phase, clock, battery level & heart rate. Tapping the a.m/p.m & 24hr will change it from 12h to 24hr clock. Enjoy wearing it as I enjoyed making it.
