MT5602-U

METAS-grade version of MT5602, introduced in 2023. Beating to a frequency of 28,800 beats/hour or 4Hz, the movement is regulated by a variable inertia oscillator with silicon balance spring, held in place by a traversing bridge - a guarantee of its robustness. Certification by the Swiss Official Chronometer Testing Institute (COSC) Precision at two temperatures, in six different positions and at two different levels of power reserve: 100% and 33%. Smooth functioning when exposed to a magnetic field of 15,000 gauss and precision following exposure
