Analog Soul. Digital Brain.
We've combined the satisfying mechanics of a traditional chess clock with the precision and features required for modern tournament play.
Microsecond Precision
Perfect for intense blitz and bullet games. Our custom timing module guarantees absolute fairness.
Modern Increments
The world's first 'analog' clock that supports Fischer increments and delay modes.
200 Hour Playtime
Outlasts most analog spring winds. Focus on your game, not your battery level.
100 Day Shelf Life
Smart sleep modes detect user inactivity, preserving battery for months of casual use.
