This automatic movement has about 50 hours of power reserve and because it is an El Primero, it operates at a high frequency of 36,000 bph. Compared to other popular chronograph movements, which is typically 28,800 bph. This allows the watch to have the ability to be more accurate over time, and allows the chronograph to measure more precise increments of time. NO RESERVE 不設底價
