Citizen adds a new blue-dialed chronograph to its Eco-Drive lineup, featuring the Caliber B620 movement and a mid-size case. We examine the specs, pricing, and how it compares to other solar-powered chronographs on the market.
Citizen's Eco-Drive collection is expanding with the new Chrono Racing CA4716-50L, a watch that blends a motor-racing-inspired design with the brand's established solar-quartz technology. This release focuses on a specific aesthetic—deep blue with vertical striping—while maintaining the practical, light-powered movement that defines the Eco-Drive line.

What's New: Design and Core Specifications
The CA4716-50L is built around a stainless steel case measuring 39.5 mm in diameter and 12.3 mm in thickness. This sizing is notably more restrained than many racing chronographs, which often push past 42 mm. The mid-range profile aims for versatility, making it a potential daily driver rather than a statement piece. The dial is the primary visual differentiator: a deep blue base with vertical striping and a classic three-sub-dial layout for the chronograph functions.
At the heart of the watch is the Caliber B620 Eco-Drive movement. As a solar-powered quartz movement, it converts both natural and artificial light into energy. On a full charge, it maintains a power reserve of approximately 9 months under normal use. The movement includes a 1/5-second chronograph capable of measuring up to 60 minutes, a 24-hour sub-dial for AM/PM distinction, and a date window positioned between the 4 and 5 o'clock markers. It also features standard Eco-Drive protections: an insufficient charge warning and an overcharge prevention function.
From a materials standpoint, the watch uses a mineral crystal for the dial window. While mineral glass offers higher impact resistance than sapphire crystal, it is more susceptible to surface scratches over time—a consideration for a watch intended for daily wear or active use. The watch is rated for 10 ATM (100 meters) of water resistance, making it suitable for swimming and surface aquatic activities. It comes paired with a stainless steel bracelet with a secure closure.
How It Compares: The Solar Chronograph Landscape
The CA4716-50L enters a competitive segment of solar-powered chronographs. Its primary advantage is Citizen's proven Eco-Drive technology, which eliminates the need for battery replacements and offers a reliable, low-maintenance timekeeping solution. The 9-month power reserve is competitive within the solar-quartz space.
Compared to larger racing chronographs (like some from Seiko or Tissot), the 39.5 mm case size is a significant differentiator. It caters to users who prefer a more classic, wearable diameter. However, the mineral crystal is a point of compromise; many watches in this price range, particularly from brands like Seiko, often use Hardlex or even sapphire in some models, offering better scratch resistance.
In terms of pricing, the watch is listed at S$523.20 in Singapore (approximately $411 USD) and around €219 on third-party EU channels like Larrabe. This positions it in the mid-range segment, competing with other solar chronographs and entry-level automatic chronographs. The value proposition hinges on the combination of solar technology, a specific design aesthetic, and Citizen's reputation for durability.

Who It's For: Practical Buyer Guidance
This watch is best suited for individuals who want a chronograph with minimal maintenance. The Eco-Drive movement is ideal for those who dislike changing watch batteries or owning an automatic winder. The design appeals to fans of racing-inspired watches but who find larger cases cumbersome. The blue dial and vertical striping offer a distinct look that stands out from more common black or silver chronograph dials.
However, potential buyers should consider the trade-offs. The mineral crystal, while impact-resistant, will likely show fine scratches with daily wear. If scratch resistance is a priority, sapphire crystal alternatives might be worth exploring, though they often come at a higher price point. The 10 ATM water resistance is adequate for most activities but not for serious diving.
For those considering the purchase, it's advisable to check the official Citizen Watch website for the most current specifications and availability. The watch can also be found on various online retailers, though pricing and availability may vary by region.
In summary, the Citizen CA4716-50L is a focused release that leverages the brand's solar technology within a specific design language. It offers a practical, low-maintenance chronograph option for daily wear, with the trade-off of a mineral crystal and a design that may not appeal to all tastes.
