Free to use; extras unlock with a one-time purchase. A 24-hour sun dial with the real moon. One sun marker goes round the dial once a day, over a band painted with today's daylight, nautical twilight and night where you are, so the shape of the day changes with the seasons. The round window shows today's moon at its real phase. Made for the Instinct 2, 2S, 2X, 3 Solar and E (40/45 mm) and the Descent G1, and also on round fenix, Enduro, tactix, quatix, Forerunner, MARQ, Descent Mk2 and vivoactive watches with a memory-in-pixel screen, where the dial fills the screen and the moon sits inside it. - The dial: noon at the top, midnight at the bottom, sunrise on the left, sunset on the right. Day is open, nautical twilight is drawn as fine lines, night is solid. - The sun marker shows the time on the dial; a small digital time sits in the middle (you can turn it off). - The moon in the round window, drawn to its real phase with its seas, turned the way you see it from the southern hemisphere when you are there. - The moon track: a thin arc outside the dial over the hours the moon is up today. - Four slots beside the dial: sunrise, sunset, heart rate and steps by default. - Battery, phone and unread notifications, and the date. Sun and moon times are computed on the watch from your last GPS position (or the weather location), so they work offline. Without a position the dial shows only its outline and the times show --:--. Customize it in the Connect IQ app. The round window (the moon or a value), the digital time and white on black (instead of black on white) are free to set. The four slots and the moon track (marked with a star in the settings) can be changed during a 7-day trial, and stay unlocked for good with a one-time purchase ($3.99) at murmurgram.gumroad.com/l/daywheel: enter the 12-character Watch face ID from the settings at checkout, and type the key you receive by email into Unlock key. After the trial the slots return to their defaults and the moon track is off until unlocked. Slots can show sunrise, sunset, moonrise, moonset, moon illumination, day length, nautical dawn and dusk, heart rate, resting heart rate, steps, altitude, barometric pressure, wrist temperature, weather temperature, Body Battery, stress, recovery time, Intensity Minutes, ascent today, calories or distance today. - Time font: five more styles for the time besides Jost: condensed, dot matrix, segment, stencil and outline. Privacy: everything is computed on the watch. Nothing is sent anywhere. If you buy the unlock, Gumroad handles the payment and your email address is used only to send your key and for support. Permissions are used for sensor history (altitude, temperature, Body Battery, stress, pressure, heart rate), user profile (resting heart rate), and position (sun and moon times). Time digits use Jost by Owen Earl (indestructible type*) and the Jost Project Authors (SIL Open Font License 1.1).

A starred Time font setting gives a choice of six time fonts (Jost stays free).
