A new chronograph scheduled to be released on April 9, 2026 in the Citizen Collection men's lineCA4764-57Awill be added.
This is a 1/5 second chronograph model equipped with Cal.B620 EcoDrive.The shiny, brightly colored metal dial and partial accents of jet black plating create a sporty and sophisticated look at the same time. The lugs are designed to be thick and short, and the bezel is designed to be wide. Furthermore, the attention to detail in writing the tachymeter numbers horizontally makes this model stand out from other chronographs in its category.
The rationality of the design, in which the three sub-dials also function as daylighting panels and convert light into electrical energy, is also interesting. It has a perfect balance of functionality, design, and price that will make you think, ``Isn't this one bottle enough?''
A sports chronograph that gives off a strong presence even when lined up or viewed.
Metal dial x horizontal tachymeter—a sporty aesthetic in the details.

■ “Light design” created by metal dial and subdial
The dial of CA4764-57A has a metal finish that pursues luster and good coloring. It has a depth of shine that ordinary printed dials do not have, and shows a uniform beauty both under fluorescent lighting and natural light. What is also noteworthy is that the three sub-dials also function as lighting panels. Its dual structure embodies the cleverness of eco-driving technology, as it has a strong presence as a design accent while also playing a practical role in converting light into electrical energy.
The bi-color finish with jet black plating applied to part of the case condenses the cleanliness of silver and the fearlessness of black into one. It has a spaciousness that naturally blends into any outfit, whether it's a suit or casual wear.
■ The tachymeter's commitment to "horizontal writing"
Generally, tachymeter numerical values are written vertically, but CA4764-57A intentionally uses horizontal writing. This may seem like a small detail at first glance, but by creating a consistent visual rhythm, it has the effect of greatly enhancing the sporty look of the bezel. The high level of attention to detail in the design is a distinctive feature in this price range.
The approach to form is similar, with thick and short lugs and wide bezels. The luster of the metal dial stands out even more precisely because the ``skeleton'' of a sports watch has been carefully constructed.
■ “Stress-free operation” with eco-drive x 9-month drive
Cal.B620 is an eco-drive movement that converts sunlight and indoor light into electricity to keep the watch running. The battery life when fully charged is approximately 9 months, and regular battery replacement is not required. The accuracy is stable with a monthly difference of ±15 seconds, which is typical of quartz, so you don't have to worry about accuracy control in daily use.
It is also equipped with a quick start function, so even if it is fully charged, it will start working immediately by exposing it to light. This is a piece where you can feel the design philosophy that is intended to be worn every day.
■ “Serious to practical use” with luminous x wide aperture date window
Both the hands and indexes are luminous to ensure visibility in dark places. By adding an anti-reflective coating to the sapphire glass, reflections in bright places are also minimized. The design of the date display aperture is designed to make the text appear larger and improve visibility, making this watch perfect for daily use. It is also waterproof to 10 ATM, so you can use it without hesitation in active situations.

■ Buyer's comment
When I looked at the CA4764-57A, I honestly felt that it was made with too much care. The horizontal tachymeter notation, the luster of the metal dial, and the jet black accents all convey the company's determination to not settle for just the price. The practicality of eco-driving means you don't need to replace batteries, and it can be used in a wide range of situations, from everyday business to sports. This is one that I would confidently recommend to anyone looking for a chronograph.
