New color variations to be released in April 2026 for the Citizen Collection CA4764 chronograph seriesCA4764-57Ehas been added.
It is a two-tone combination of jet black coating on the case and silver stainless steel band, which is a bit different from CA4764-57A (all jet black). The contrast created by the black case and silver bracelet gives off a solid personality while blending into your outfit.
The CA series has the same power configuration as photovoltaic power generation by Cal.B620 Eco Drive x 1/5 second chronograph x horizontal tachymeter layout. For those who think that ``all black looks a little heavy'' or ``but regular silver is not enough,'' this two-tone color may be the perfect answer.

Black dial x horizontal tachymeter writing - the sporty look stands out even more with the two-tone design.

■ “Elegant personality created by the two-tone effect” of jet black and silver
While the CA4764-57A has a ``stoic black'' case, bezel, and bracelet all made of jet black, the CA4764-57E has a jet black coating applied only to the case, and the band is finished in silver stainless steel. This choice creates a bright contrast line that runs along the border between black and silver—a classic and sophisticated look, just like a two-tone mechanical watch.
It's not as strong as the all-black model, but it has a more toned-down look than the regular silver model. For those who want to choose a chronograph that is uniquely their own, but also want one that won't stand out at work or at ceremonies, the balance of the CA4764-57E will appeal to them.
■ Tachymeter horizontal writing x black dial——CA4764 series design philosophy
One of the design features of the CA4764 series is that the tachymeter numbers are written horizontally. In a typical chronograph, the tachymeter numbers are often written vertically along the circumference, but by intentionally writing them horizontally, we have achieved both ease of reading and visual individuality.
The black dial has a shiny metallic texture and three sub-dials that absorb light and convert it into electricity for Eco-Drive. Luminous hour and minute hands and indexes ensure visibility in dark places, and the more you use this model, the more you will notice the attention to detail.
■ Differences with CA4764-57A—Which one to choose?
The biggest difference between CA4764-57A (all jet black) and 57E is the band color. The 57A has a PVD black bracelet that perfectly matches the case, creating a cool and sharp all-black worldview. On the other hand, 57E is two-tone with a silver bracelet, making it more versatile and goes well with any coordination.
CA4764-57E wins in terms of being less distracting in formal situations and easy to match with bright outfits. Choose the two-tone 57E for those who want to match any style depending on their mood, or the 57A for those who like the cleanliness of all black.Please choose according to your preference and purpose.

■ Buyer's comment
When I first saw the CA4764-57E, my honest impression was that it was easier to use than the 57A. The jet black case is cool, but I sometimes choose to coordinate it with all black. However, the 57E is two-tone with a silver bracelet, so it blends naturally with both suits and casual wear. The cool design of the horizontal tachymeter and black dial is common to the series, and the practicality of Eco Drive and sapphire is also perfect. I think it's a well-balanced book.
