I am using the GMT Watch Face. I like the fact that by rotating the crown I can see the times of various cities in the world. However I cannot understand the function of the red colored hand. Also below the 12 o clock position’RIK’ for Rikitea, PF is always displayed. Let me know if I can change it to display the name of another city so that I can easily see dual time of my choice by tapping on the city name on the watch face. Otherwise I find this watch face very useful.
