Urwerk launches Atomic Master Clock – a master clock and wristwatch combo

The AMC, short for "Atomic Master Clock", to be released later this year, is a master clock and slave wristwatch combo that will keep your watch in tip-top timekeeping condition - without you having to lift a finger Alessandro Bisagni senses the clock ticking down on climate change An atomic clock's timekeeping aspect is based on energy wavelengths emitted by certain atoms as they travel between energy states.

Urwerk's atomic master clock, created in collaboration with TimeStandard, uses ions of YIG and rubidium, and has been manipulated to be used at any voltage The outcome is a timekeeping clock accurate to within one second in 317 years The idea for a "Master clock" dates back to 1793 when Abraham Louis Breguet devised an idea for a "Sympathique clock" that kept designed watches in time by correcting them to an accurate standard time.

The slave watch, designed to fit the AMC, is included. . Source
