It's small changes to the design that increase ease
link of use and tactile quality. For instance, the bezel uses a "labyrinth seal" between
link the bezel and the case so simply turning the bezel while rinsing the watch will eject any sand or particles that get between the case and the bezel. And the bezel mechanism is a double-piston design that
link uses 16 ball bearings, which means that bezel action is silky smooth.
