Citizen Atessa ACT Line is a 3-hand model with a compact octagonal case.CB3040-56Hwas added in March 2026.
The dial combines a super titanium case with a hairline molding pattern and metallic paint—a delicate finish reminiscent of a single piece of metal that stands out with the clean, one-tone silver tone. This is a product that has the three pillars of functions: Eco Drive radio waves (H128), Direct Flight, and Perfectex, all within a price range of 99,000 yen (tax included).
The balance between the sharp presence of the octagonal shape and the compact 40mm size that fits into the cuff of a suit can be felt as soon as you put it on your arm. ``Easy to use and cool'' - this model was designed with serious consideration given to achieving both.
When placed on your arm, its handsome appearance stands out.
Even if you line them up or look at them, they are beautiful.

■ “Sporty coolness” created by the octagonal case
The biggest feature of CB3040-56H is its compact octagonal case shape. The octagon, which is neither round nor square, has an increased number of faces, allowing for a rich variety of hairline and mirror finishes, giving it a variety of expressions depending on how the light hits it. The size of 45mm in height x 40mm in width makes a strong statement, yet fits well into the cuff, making it a perfect balance with suit style.
The dial is a special specification with a hairline molded pattern and a layer of metallic paint. The homogeneous and deep texture reminiscent of a single sheet of metal is difficult to convey in photos, but many people are surprised at the high level of perfection when they hold the real thing in their hands. A clean look with one silver tone - the epitome of sophistication.
■ “The pinnacle of materials”: super titanium x Duratect titanium carbide
The case and band are made of Citizen's proprietary super titanium. Although it is approximately 40% lighter than stainless steel, the surface hardness is increased by more than 5 times with Duratect titanium carbide coating. Weighing approximately 88g, it is exceptionally light for a full-metal business watch, and is designed to reduce strain on your wrists even when you work at a desk for long periods of time or spend a lot of time on the move.
Duratect titanium carbide is scratch resistant and has a metal allergy resistant design that takes into account metal allergies. The fact that it can maintain its condition for a long time even if you wear it every day satisfies the most important requirement for a watch as a work tool.
■ Direct flight changes “ease of handling overseas time”
Direct Flight is a function that allows the hour hand to smoothly move to the desired time simply by operating the crown. The convenience of being able to quickly adjust the time difference during overseas business trips or travel destinations without complicated operations is directly linked to the daily sense of security for globally active business people.
In combination with World Time (24 hour difference), it can be used to simultaneously check the current location and the time in another city. Radio wave reception is compatible with Japan, China, America, and Europe, and the time is automatically corrected even when you are on a business trip. This design eliminates the stress of ``noticing that the time has changed.''
■ “Everyday precision” protected by Perfectex and sapphire glass
Citizen's original technology "Perfex" is a mechanism that integrates three functions: JIS class 1 magnetic resistance, shock detection function, and automatic needle correction function. Even if the hands become misaligned due to a strong magnetic environment or an unexpected shock, they are automatically corrected, allowing you to continue displaying the accurate time every day with confidence.
The sapphire glass is designed with an anti-reflective coating to minimize reflections and allow for clear visibility of the dial. The power save drive has a long life of approximately 2 years when fully charged, and the fact that regular battery replacement is not required is a major strength of Eco Drive.

■ Buyer's comment
I believe that the CB3040-56H is "the easiest to choose as an entrance" among the Atessa ACT Line. The sharpness of the octagonal case and the high quality of the metallic dial give a sense of satisfaction that exceeds the price of 99,000 yen.
