c. solar

A revival of Circa Solar, the 24-hour clock that follows the sun


c. solar brings back Circa Solar — a 24-hour watch face originally designed by Ted Hunt, discontinued after its run on the App Store. Instead of hours and minutes, one hand sweeps a full day: midnight at the top, noon at the bottom, sunrise and sunset marking the sides, with the day/night split shifting through the year as the seasons and your location change.

Rebuilt as a web app with three switchable faces — Circa, the most faithful recreation and the one that credits Ted Hunt directly; Clear, with hour numerals for a more legible read; and Poetic, the original’s amber-and-dusk palette. Open source under MIT.
