Star Wheel is a watchface designed to show a realtime planisphere (star map) based on the user's current location and time. The planisphere updates its rotation every minute and is labeled with cardinal directions to assist in finding visible constellations and stars. Stargazer and astronomy-focused users can use this as a quick reference to the visible stargazing conditions.

The planisphere is drawn according to the current latitude, rotated according to the current time, and the viewing window ellipse is dynamically calculated based on the user's current expected stargazing visibility. Optional dynamic labels may be displayed for six of the most important constellations in each hemisphere. (Best results are expected at latitudes beyond the tropics; users within 20 degrees latitude from the equator will experience less accuracy of star mapping due to the inherent limitations of planispheres.)

An optional fullscreen view mode renders a centered planisphere in the middle of the screen. In this view setting, rotation and the starmap image remain accurate, but all stars are displayed rather than a viewing window ellipse representing the stars currently visible in the horizon.

Additional features include: an optional second time zone location which can be set and displayed at the bottom of the star map, a lunar phase icon indicating the current phase of the moon, and a rotating month ring indicating annual progress.

A data bar in the top right can display battery status, daily steps progress, move bar, or be toggled off.

There are 4 customizable data fields with user choices to display any of the following: Sunrise/Sunset, Heart Rate, Respiration Rate, Intensity Minutes, Active Calories, Daily Calories, Pulse Ox, Steps, Floors Climbed, Distance, Altitude, Notifications, Weather High/Low Temp, Weather Current Temp, Body Battery, Stress, Barometric Pressure, Recovery Time, Wind Speed, Wind Direction, Running Distance, Cycling Distance and Battery Percentage.

Further user options include radial or numeric seconds display, Bluetooth status icon, and grayscale datafield icons.
