In order to make the watch material stronger, Citizen has developed Duratect surface treatment process. By special processing of materials such as stainless steel and titanium , the surface is made harder to cope with scratches caused by the watch during daily use. While achieving different degrees of hardness, Duratect can also perform metal coloring: silver, black, gold and other colors can be achieved, providing more possibilities for watch design. Recently, Citizen launched three "Blue Universe" series watches, using the newly developed new Duratect DLC Blue color, adhering to the fusion of technology and beauty, bringing a new color experience.

Citizen works with ispace, which is responsible for Hakuto-R commercial lunar exploration project, to provide Shubo™ titanium components support for the leg bracket of the lunar lander. Citizen's Shubo™ Titanium is about to embark on a dazzling journey to space, and the design inspiration for the "Blue Universe" series is derived from the twinkling stars of the universe. The body parts of the three watches use the newly developed DLC Blue spot color, which retains all the advantages of Duratect DLC and gives it a unique dark blue tone. During the development process, Citizen adopted the principle of film interference, a phenomenon similar to the appearance of iridescent light wave interference on the surface of soap bubbles. Citizen's continuous research and development of Duratect surface treatment technology over the past decades has injected a new visual experience and wearing experience into the new watch, making it more wear-resistant while also having an attractive dark blue color and a smooth and shining surface.

"Blue Universe" series watch CC4066-69E. The watch body is all made of Citizen's unique space material Shubo™ titanium, which mainly uses celestial colors to add a sense of high-end and refined to the overall watch. Dark gray and dark blue strap is presented in two processes: dark gray and quiet, using Duratect DLC process; dark blue is elegant, using Duratect DLC Blue new color process. The bezel design is more sophisticated. The U-shaped outer ring, which also uses the new DLC Blue craftsmanship, is embedded in sapphire glass , engraved with the world city abbreviation with black background and white characters, which is clear and clear; the blue inner ring and black dial, paired with silver-white hand scale, are like a cool moonlight that suddenly appears in the dark night, making people feel stunning. Double spherical sapphire glass is like a sky curtain, and the anti-reflective coating makes it clearer when reading.

Functional, CC4066-69E is equipped with a photokinetic GPS satellite-to-time movement F950, which can receive the signal proofreading time of GPS navigation satellite 20,000 kilometers away from the earth, and can complete the reception of time signals within 3 seconds at the fastest. The dual-coil high-speed motor allows the hour and minute hands to rotate faster, allowing the current time to be displayed quickly. In addition, it also has a timer function in 0.05 seconds, up to 24 hours, as well as a number of complex functions such as alarm, off-site time, daylight saving time, , perpetual calendar, etc.

The other two watches in the "Blue Universe" series, AT8187-75E and CB0217-71E, also adopt the new DLC Blue color process. The design is still mainly space color, with slightly different dial layouts, and different traditional and simple. Both watches are equipped with a multi-game radio wave movement, and receive the signal transmitted by the radio wave tower to automatically proofread the time and date. In addition, the time display, perpetual calendar, residual power display and other functions meet daily needs. Antimagnetic, impact detection, and pointer correction are three major protective functions to protect the watch from magnetic field and pointer displacement after impact.
The vast universe brings endless imagination and creativity; the colors of celestial bodies merge naturally reflect thousands of images. The three "Blue Universe" series watches show the vast universe with celestial colors, and the dial is made of black gold, meaning the twinkling stars in the universe. With a century of technological heritage, Citizen brings space technology together at the wrist and creates infinite charm.With "Better Starts Now" as the brand belief, Citizen always believes that there are still infinite possibilities ahead to make the world better, and this is the beginning.
