Description
Why is it that nearly every time ? appears in a formula it is preceded by a 2? Pi has been a key to mathematics at least since Archimedes, but it’s under attack from a valiant opponent: Tau. Equivalent to 2?, ? makes a more natural mathematical constant, because it is based on the defining feature of a circle: the radius.
This watch is based on unit circle diagram using dozenal notation and the ? circle constant (tau).
