Hands-On: The A. Lange & Söhne Richard Lange Jumping Seconds

The A. Lange & Söhne Richard Lange Jumping Seconds features a rare combination of three time displays and three technical complications. Its jumping seconds mechanism uses a five-pointed star to advance the seconds hand in precise one-second intervals. A remontoir provides constant force to the movement, releasing equal energy once per second to ensure consistent timekeeping. The watch also includes a power-reserve indicator that turns red when less than 10 hours remain, and a zero-reset mechanism that returns the seconds hand to zero when the crown is pulled, allowing for exact time setting.
