Tap the centre knob to change the background tartan pattern. There are 11 patterns to choose from so there are higher chances of matching your watch face to your clothes. Tap actions on the date and 5 icon buttons will launch the calendar, Samsung Health, messages, timer, music and weather apps. Tap actions were tested on a Samsung Galaxy Watch and may not work on other smartwatches. If the tap action for timer does not work because there is no timer app in your Samsung watch, please try installing the free timer app from Samsung Electronics. The tap action should work once the timer app is in your watch. The app can be downloaded from Galaxy Store under the watch apps category. A big Thank You to dooks2 for the Transitions Watch as I learned the multi-screen switching script from it.
