CITIZEN Eco-Drive Super Titanium Zenshin Senkei CA4690-51A is a chronograph watch that uniquely combines Japanese tradition with modern innovation. As its name suggests, Zenshin stands for progress and advancement, while Senkei refers to clean lines – values clearly reflected in the watch’s design and finishing.
The entire watch is crafted from Super Titanium™, making it exceptionally durable while remaining extremely lightweight and skin-friendly. The updated case design adds sharper lines and a modern 41 mm diameter. A refined white dial is protected by scratch-resistant sapphire crystal. Weighing only 97 grams, the watch features a Super Titanium™ bracelet with a secure fold-over clasp for excellent wearing comfort.
At the heart of the watch beats Citizen’s in-house solar-powered Eco-Drive movement, caliber B620-00M, offering up to nine months of power reserve when fully charged. The chronograph functions include a stopwatch measuring in 1/5-second increments up to 60 minutes, a 24-hour subdial, and auxiliary dials at 3 and 9 o’clock. What sets this model apart, however, is the small seconds subdial at 6 o’clock – highlighted with a contrast color for improved legibility and visual distinction.
The watch also features a date display, power reserve indicator, and outstanding accuracy with a monthly deviation of only ±15 seconds. With a water resistance of 10 bar (100 meters), it’s suitable for swimming and water play, though not for diving. The round case in titanium white finish and the minimalist baton-style indexes complete the watch’s understated yet modern appearance.
CITIZEN Eco-Drive Super Titanium Zenshin Senkei CA4690-51A is more than just a timekeeper – it’s a daily companion where technical excellence, visual clarity, and practicality converge. Designed for the man who values precision, comfort, and minimalist aesthetics – and who embraces the spirit of continuous progress this watch proudly represents.
