Does it really never need a battery?

Yes. Eco-Drive is a solar movement that charges from natural or artificial light and stores the power in a capacitor, so there is no battery to replace.

How big is it on the wrist?

The case is 32 mm across, which is a small, dressy size. It sits close to the wrist and suits narrow wrists better than a large chronograph would.

Is the dial real mother-of-pearl?

The dial is mother-of-pearl with gold-tone accents and chronograph subdials. Each dial varies slightly in tone, which is normal for the material.

It is built for everyday water resistance rather than diving. Avoid pressing the chronograph pushers while the watch is wet.

The watch on its stainless steel bracelet, a Citizen box and paperwork. Check the listing for the exact contents.

How does it compare with a battery-powered fashion chronograph?

It costs more upkeep-free: no battery changes, a steel case and bracelet, and a real chronograph. A fashion chronograph may offer a larger case and bolder styling for less.
