| Citizen expands its Eco-Drive lineup with two new two-tone chronographs |
Citizen Watch Co. has just expanded its popular AT2600 series with two striking new additions that are turning heads across Asian markets. The Japanese watchmaker unveiled the AT2604-56H and AT2604-56X, a pair of sophisticated chronographs that combine the brand's legendary Eco-Drive technology with eye-catching dual-tone aesthetics.
These new releases join the AT2600 series family, which originally debuted with three models back in May, but the latest offerings bring something distinctly fresh to the table. With their premium gold-toned accents and richly textured dials, these timepieces represent Citizen's continued commitment to delivering exceptional value in the accessible luxury segment.
A Closer Look at the New Models
The AT2604-56H features a versatile 41mm stainless steel case paired with a warm gold bezel that immediately catches the light. Gold-toned Roman numerals, hands, and pushers complement the bezel perfectly, creating a cohesive design that exudes understated elegance. The charcoal grey textured dial provides a sophisticated backdrop, bearing a striking resemblance to the dial found on the previously released AT2600-57E.
On the other hand, the AT2604-56X makes a bolder statement with its emerald green textured dial. The green surface creates a stunning contrast against the gold bezel, hands, and numerals—a combination that feels both contemporary and timeless. This model is likely to appeal to collectors seeking something that stands out from the crowd while maintaining Citizen's signature refinement.
Both watches come equipped with:
- A dual-tone stainless steel bracelet with a convenient fold-over push-button clasp
- Durable mineral crystal that resists scratches from daily wear
- A slim 11mm profile despite the complex chronograph movement inside
- Comfortable 153-gram weight that sits well on the wrist
The Heart of the Watch: Eco-Drive Technology
Under the hood, these chronographs are powered by Citizen's reliable H504 Eco-Drive calibre—a solar-powered movement that represents the brand's commitment to sustainable watchmaking. What makes this movement truly remarkable is its five-month power reserve when fully charged, ensuring your watch keeps running even when you're not wearing it.
The Eco-Drive technology charges continuously from any natural or artificial light source, eliminating the need to ever replace the watch battery. This means fewer hassles and less environmental waste over the lifetime of the watch. Practical features like the insufficient charge warning and overcharge prevention function give you peace of mind, letting you know when your watch needs a quick dose of sunlight.
Functionality Meets Elegance
The dial layout offers excellent readability with three subdials displaying:
- Elapsed chronograph minutes for timing events
- A 24-hour clock for distinguishing day from night
- Running seconds for precise timekeeping
A practical date display sits at the 4 o'clock position, adding everyday utility without cluttering the dial. The chronograph function allows you to measure elapsed time with precision, making these watches suitable for everything from tracking your morning run to timing important business presentations.
Despite the mechanical complexity inside, Citizen has managed to keep the case remarkably thin at just 11mm—a testament to their engineering prowess. With water resistance rated at 10 bar (100 meters), these watches can handle swimming and snorkeling, though they're not designed for serious diving.
Asian Market Exclusivity
For now, Citizen's latest chronographs remain exclusively available in select Asian markets—specifically Singapore, India, and Vietnam. The pricing strategy reflects regional considerations, with both models retailing at SG$561.35 in Singapore and ₹39,900 in India.
In Singapore, you can explore the AT2604-56H model at Citizen Watches Singapore, where watch enthusiasts can get a closer look at the specifications and place orders.
For those in Singapore interested in the emerald green variant, the Citizen Singapore official website provides detailed product information and purchasing options.
Will These Come to Global Markets?
Watch enthusiasts in the US, UK, and Europe may be wondering if these stunning pieces will make their way westward. As of now, Citizen hasn't announced any plans for a global release, which means these models could remain Asian exclusives—at least for the foreseeable future.
This limited availability adds an element of exclusivity that collectors often appreciate. For those passionate about unique timepieces, these watches represent an opportunity to own something that isn't readily available everywhere. However, it's worth noting that Citizen frequently monitors regional demand and has been known to expand availability based on market response.

Frequently Asked Questions
What is the difference between the AT2604-56H and AT2604-56X?
