The high-accuracy Eco-Drive model (AQ4091-56M) has annual accuracy of ±5 seconds, as well as a case and band made of Super Titanium™.

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 case is made of Super Titanium™ *2 finished with CITIZEN’s proprietary surface hardening technology Duratect *3 Platinum that provides a bright metallic hue. 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. One of the most impressive features is the perfect alignment of the second hand and indices when viewed from the front. The Caliber 0100 model (AQ6110-10L) is powered by Eco-Drive and has an annual accuracy of ☑ second.

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 delicate Japanese paper allows light to reach the Eco-Drive movement while also providing a beautiful texture in an appealing range of colors. Washi paper dials were first featured on The CITIZEN watches in 2017, giving our Eco-Drive models a new kind of visual appeal.
