I've built a watch-face for my watch and made it public. A watch-face is the view you see when your GPS watch is in normal mode. It displays the time, the battery level, the date, a Bluetooth icon (if connected) and your daily steps. The code is open-source and hosted here. A nice remake has been made and hosted here. The watch-face is available for download at Garmin Connect IQ.
