The Citizen CB5860-27E Promaster Sky is a fully radio-controlled watch. This Citizen is controlled by the transmitter signal of the atomic clock. So you never have to time the watch yourself. Another advantage: it runs very precisely, the deviation is only 1 second per 1 million years! This watch also automatically adjusts the time when you travel to a different time zone.
The Promaster Sky CB5860-27E features a light-sensitive cell that draws energy from artificial light and sunlight. Very nice is also that this watch is equipped with anti-reflective sapphire crystal that provides excellent protection against scratches and damage.

The equipment Citizen has given this watch can certainly not be called meagre: an infinite calendar, world time, 24-hour display and stopwatch make this watch a multifunctional piece of jewellery.
The fine leather watch strap wears smoothly and matches the dial very well.
