Does it really never need a battery?

It uses Citizen's Eco-Drive solar movement, which charges from light. The rechargeable cell lasts many years, but it is not literally eternal.

44mm is on the larger side. It suits medium to large wrists; if you usually wear 38-40mm watches, try it on first.

Is it good for swimming?

It is water resistant, which covers splashes and handwashing. Check the caseback rating before swimming or diving.

Typically the watch, a Citizen presentation box and paperwork. Confirm the listing includes the box and warranty card.

Is $239 a good price?

At $239.00 at eBay as of November 5, 2026, it sits at the low end for this Eco-Drive chronograph. Compare the other new listing before buying.

Our take on the Citizen Men's Eco-Drive CA4505-21X Watch

The Citizen Eco-Drive CA4505-21X is a 44mm analog chronograph with a solar-powered quartz movement, so it charges from light and never needs a battery change. It has a round case, a scratch-resistant crystal and water resistance for daily wear. The best new price is $239.00 at eBay as of November 5, 2026, and two stores list it new.
