Yay pi watch! The Cadence Radian Chronograph is the ideal timepiece for classier math fans and stylish geeks. Combines an accurate three-dial chronograph with the subtle Archimedean spiral and radian unit measurements of the classic Radian watch.
"Radian Watches combine the unit circle with the 12 hour dial. I hope you already know how to tell time, so we stuck 0 at the 3 o'clock position like it belongs and the radians count up counter clockwise [though the watch hands move clockwise, obviously]. I called out the angle measurements at each of the hour positions and stuck the eighths in there too. In the background is the subtle Archimedean spiral, because it looks cool and graphs the equation r = a + bθ." — Christopher Thompson, Radian watch designer
