To access the settings of the watch face, you can find them in the "Wear OS" app on your mobile device. Simply tap on the gear icon over the watch face preview to access the settings screen.

The free settings of Qirex Watch Face allow you to customize design colors on both the watch and mobile, define the refresh rate for heartbeat frequency and weather, choose between 12 or 24-hour mode, and more.

There are also premium settings available for purchase, which allow you to further customize the watch face with your own title, choose different background styles, define a secondary timezone, and more.

For additional customization options, you can use the optional phone app, which provides settings for card styles (Wear 1.5x only), weather providers, location preferences, and more.

Overall, Qirex Watch Face offers a range of customization options for Wear OS users, allowing them to personalize their watch face to their liking.
