Superior precision meets the highest standards of quality in The CITIZEN. Representing the never-ending pursuit of the essence of the watch, this exceptional Super Titanium™ timepiece serves as the ideal all-purpose timepiece, perfectly balancing mechanical refinement with aesthetic intrigue. The CITIZEN watches are crafted in a dedicated workshop deep in the Nagano countryside, where extraordinary skill is essential for their highly advanced movements. This meticulous work is entrusted to our watchmaking Meisters, our most experienced and technically proficient artisans. With precision and care, they bring each timepiece to life, making every watch a true reflection of Citizen craftsmanship.

The ultraprecise Citizen Caliber 060 movement was developed using only the most rigorously selected crystal oscillators and is assembled from individual components of extraordinary precision. With an annual accuracy of ±5 seconds, the crystal oscillators were set aside for a six-month observation period before selecting only those that meet Citizen’s demanding standards of accuracy.

On the wrist, the watch measures comfortably at 38.3mm, with its silver-tone Super Titanium™ case that’s lightweight, scratch- and rust-resistant, and faceted with sharp surfaces of brushed and polished finishing and secured via a matching triple-link bracelet. A dual-sphere sapphire crystal protects a unique black dial with an eagle feather pattern, creating a captivating interplay between light, texture, and color. Towards the bottom of the display is an eagle mark, symbolizing the twin ideals of The CITIZEN – foresight and dedication to the pursuit of ideals, as well as the enduring connection between watch and wearer.

Equipped with our proprietary Eco-Drive technology that's sustainably powered by any light and never needs a battery, advanced features include a perpetual calendar, a 60-hour power reserve and power reserve indicator, time difference correction, and a midnight sharp calendar update function. Water resistant up to 100 meters.
