Our paradigm at KRYPTON is relatively simple: our watches are a reliable companion even when times get tough. That is why we rely on the ETA movement 2824-2 with its relatively simple but highly effective construction. This movement is - and here we quote - "the essence of a work horse and is characterized by its high reliability and durability." The movements wind themselves automatically through ball-bearing rotors that translate the movement of the internal levers into mechanical tension. The balance wheel - the heart of a mechanical watch - then works with a constant beat of 28,800 half-oscillations per hour. In order to minimize wear and friction of the moving parts, 25 rubies are used to allow for a power reserve of 36 to 40 hours. Which means that the watch – fully wound up and without any arm-swings - can not stop until this time has elapsed.
