New Watch Face Format for Wear OS 4

According to Google’s blogpost, Samsung and Google built a format called “Watch Face Format,” for developers and designers so they can easily create high-quality and power-efficient watch faces for Wear OS 4.

The Watch Face Format is a new way to build watch faces for Wear OS smartwatches, developed in partnership with Samsung.

The format is a declarative XML format that does not involve any executable code, meaning that the Wear OS platform takes care of the logic needed to render the watch face.

This means that watch face designers will no longer have to worry about code optimizations or battery performance as Wear OS will handle the rendering logic. As a result, maintenance and updates will be reduced, and designers will benefit from the latest bug fixes and performance enhancements without updating the watch face.

The Watch Face Format lets designers create analog and digital watch faces, watch faces with complications, customizable watch faces, and more. Here are some examples.

Analog and digital watch faces:

Three watch faces illustrating different analogue and digital styles.

Watch faces with complications:

Three watch faces displaying different complication formats.

Customizable watch faces:

Three instances of the same watch face displayed in different color choices.

And more…

A planets-based watch face, a rainbow-inspired watch face and one based on the sun and moon

Samsung’s Watch Face Studio is an alternative to directly writing XML using the Watch Face Format, and makes it easy for designers to create watch faces without any coding experience.
