The CITIZEN High accuracy watches with light-powered Eco-Drive*1 New models with hand-dyed indigo washi paper dials
CITIZEN’s The CITIZEN models provide superior precision and high quality, symbolizing the company’s never-ending pursuit of the essence of the watch. Two new models will be released from this collection featuring hand-dyed indigo washi paper on the dial. The first is equipped with the world’s most accurate light-powered movement - the Caliber 0100 Eco-Drive movement - with annual accuracy of ±1 second. The second features a high-accuracy light-powered Eco-Drive movement with annual accuracy of ±5 seconds.
*World’s most accurate watch as of February, 2022. Most accurate autonomous analogue light-powered quartz watch, based on research by Citizen Watch Co., Ltd.

Washi paper dials were first featured on The CITIZEN watches in 2017, giving our Eco-Drive models a new kind of visual appeal. The delicate Japanese paper allows light to reach the Eco-Drive movement while also providing a beautiful texture in an appealing range of colors. The dials of the newest additions to this collection feature Tosa washi paper, hand-dyed using traditional Japanese methods to achieve a deep, clear indigo color also known as “Japan blue.” This is the first time that CITIZEN has used hand-dyed indigo washi paper on its watch dials.
The Caliber 0100 model (AQ6110-10L) is powered by Eco-Drive and has an annual accuracy of ±1 second. One of the most impressive features is the perfect alignment of the second hand and indices when viewed from the front. Each detail of the design is a reminder of the groundbreaking technology inside, and the case lugs are inspired by the crystal that gives the movement its incredible high accuracy. The case is made of Super TitaniumTM*2 finished with CITIZEN’s proprietary surface hardening technology Duratect*3 Platinum that provides a bright metallic hue. The crocodile leather strap, certified by the Leather Working Group (LWG)*4, gives the watch a sophisticated, understated look while the transparent case back reveals the Caliber 0100 movement with its ruthenium plating and distinctive striped finish. The high-accuracy Eco-Drive model (AQ4091-56M) has annual accuracy of ±5 seconds, as well as a case and band made of Super TitaniumTM.
The eagle mark on the dial and crown symbolizes the twin ideals of The CITIZEN - foresight and dedication to the pursuit of ideals as well as the enduring connection between watch and wearer.

· Cal.0100 Eco-Drive Movement is the Most Accurate in the World
The Eco-Drive movement used in this model is a light-powered movement that maintains accuracy of ±1 second per year and is not reliant on any external time signal. It was announced by CITIZEN in 2018 on the occasion of the 100th anniversary of the founding of the company and is the most accurate in the world. CITIZEN is dedicated to the constant pursuit of new possibilities for watches while maintaining their fundamental functions. The first model using the movement was released in 2019 as the crystallization of the company’s ability as a manufacture d'horlogerie—a manufacturer that can handle everything from the production of parts to the final assembly of products in-house. The precise hand movement is achieved thanks to this ability to create precision parts powered by the revolutionary light-powered Eco-Drive and assemble them with great accuracy.

∙ AT-cut Crystal Oscillators
Astonishing precision is achieved by using AT-cut crystal oscillators, which have a frequency of 8.4 MHz (8,388,608 Hz), 250 times higher than the tuning fork-shaped oscillators used in ordinary quartz watches. AT-cut oscillators also exhibit higher resistance to the effects of temperature and gravity and change less over time. Although AT-cut oscillators were formerly unable to be used in watches due to excessive power consumption issues, because CITIZEN does everything in-house it was possible to overcome this problem by taking time to select the right materials and carrying out extensive design, testing and adjustment to improve energy efficiency. Now the oscillators can run for approximately eight months using the Eco-Drive’s Power-Save function.

∙ LIGA Process to Produce Precision Parts
The most prominent feature of Cal.0100 model watches is that the second hand accurately aligns with each of the indices when viewed from directly above. The precise action of the hands, which speaks of the beauty of each second, can only be achieved using the LIGA process* that makes processing and production of high precision parts possible. Ordinary gears and springs are usually produced using cutting or pressing processes, but this movement has a special part that consists of a uniquely shaped spring and gears made using the LIGA process. This is the key to controlling even a slightest backlash from gears and maintaining hand movement accuracy.
*LIGA process: The LIGA fabrication process is a processing technology using photolithography and electrocasting, suitable for manufacturing of ultra-precise parts and microstructure parts.

∙ Assembled by Meisters
Dedicated Meisters, who are the most skilled craftsmen at CITIZEN, take charge of assembly and ensure the highest degree of accuracy. In the final inspection, they personally check each watch using an imaging device to ensure that the second hand lines up properly with all 60 indices.

∙ Technology Maintains High Accuracy
This model is equipped with a function whereby temperature change is checked every minute, so that compensation can be made for even the slightest delay caused by a change in temperature. As CITIZEN insists on practicality, the watch is able to maintain accuracy under normal environmental conditions in many regions in temperatures ranging from 5–40°C. The circuit has a shock detector function and hand movement adjustment function, while the movement is resistant to magnetic fields. This combination of technologies makes it possible for the watch to maintain an extraordinary accuracy of ±1 second per year.
