Citizen Japan has revealed two new limited-edition watches as part of the Attesa “ACT Line,” known as the “Shades of Red” collection. Launching on February 26, 2026, this series includes two models: the BY1005-73Z and the CC4077-71Z. These timepieces celebrate an upcoming total lunar eclipse, which will be visible across Japan at 8:04 PM on March 3.
Design and Features
Both watches are made from Super Titanium and feature a Duratect DLC (Diamond-Like Carbon) coating. The dials are designed to reflect the beauty of a total lunar eclipse. Each model has radio-controlled and GPS-synchronized movements, ensuring precision in timekeeping.
The BY1005-73Z is powered by the H874 caliber. This Eco-Drive movement is radio-synchronized and boasts an accuracy rate of 15 seconds per month without signal reception. It also features a “Luna Program,” which calculates and shows the moon phase based on incoming radio signals. The dial is uniquely crafted with a pearlescent-printed base that represents a night sky, topped with a 3D inkjet-printed layer mimicking the moon’s texture. At a thickness of 10.8 mm, it remains more compact than the GPS variant. This model also offers 10 bar water resistance and is rated as “Metal Allergy Resistant.”
Flagship Model
The CC4077-71Z is the standout model in the collection, equipped with the F950 GPS-sync Eco-Drive caliber. This movement allows for a 1/20-second chronograph and quicker satellite signal acquisition, although it results in a thicker case at 15.4 mm. The dial design is intricate, featuring a wine-red moon pattern layered over a white mother-of-pearl base. A striking element is the sapphire bezel ring, which uses dual-layer vapor deposition to create deep red shades and silver city names. Despite its 44.6 mm diameter, the use of Super Titanium keeps the weight manageable at 111 g, making it a practical choice.
The Citizen CC4077-71Z is priced at ￥385,000 (~$2,461), while the BY1005-73Z is available for ￥198,000 (~$1,266) on Citizen Japan’s website. If you’re looking for something different, consider the Citizen NJ0150-56E, which can be found on Amazon.
