Citizen Radio-Controlled Watch AT8 Super Titanium, AUTOMATIC BLACK DIAL, 43mm - AT8390-55E

Radio-Controlled World Time Watch in Super Titanium
Perfect for those who travel the world, it combines three technologies developed by Citizen: Eco-Drive (light as an energy source), Radio-Controlled (radio-controlled movement), and Super Titanium™ for the case and bracelet. It also features a world time function, displaying the local time of 26 cities. Super Titanium™ is lightweight and scratch-resistant, making this model particularly suitable for everyday wear and travel.

The AT8390-55E model features a light-powered Eco-Drive movement with radio-controlled technology. It receives the local signal from an atomic clock and uses it to set itself with second-by-second accuracy: the deviation is just one second every 100,000 years.

This radio-controlled chronograph is equipped with the proven in-house H804 caliber with Eco-Drive technology. In addition to world time and radio synchronization, it offers a perpetual calendar, chronograph, power reserve indicator, and power-saving function. It is also anti-magnetic, features scratch-resistant sapphire crystal, and is water-resistant to 10 bar. The diameter is 40.5 mm, so it remains compact.

It is characterized by a case with bold lines, a textured dial, and a sporty tachymeter bezel. The inner rehaut with city codes for world time completes the design.

For those who want to explore the world without ever losing track of time, our AT8390-55E in Super Titanium™, world time, and radio-controlled is the ideal companion. It is lightweight, scratch-resistant, and combines Citizen technologies such as Eco-Drive, radio synchronization, and world time for 26 cities.
