Our take on the Citizen Men's Chronograph Watch CA4640-09A

The Citizen CA4640-09A is a men's chronograph with a 41mm stainless steel case, a white dial with black subdials, and a black leather strap. It runs on Citizen's Eco-Drive solar movement, so it charges from light and never needs a battery change, and it is rated to 100m for swimming. The crystal is mineral rather than sapphire, which is the main cost cut at this price. At $235.04 at Walmart as of November 7, 2026, it sits near the top of its recent range, so it is not a bargain moment.
