3 lovely denim patchwork patterns that I saw on the internet. Tap the centre knob to change the background pattern. There are 3 patterns to choose from. 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. All tap actions can be customized in Watchmaker app in your phone to apply your favourite watch functions.
