Citizen Eco-Drive Corso 40 mm Two-Tone

This Citizen Eco-Drive Corso is a 40 mm analogue dress watch built for adults who want a classic stainless-steel timepiece that charges from any light source. The two-tone gold-tone and silver-tone case and bracelet suit both formal and casual wear.

Suits daily wearers wanting solar charging

The watch fits anyone looking for a low-maintenance accessory that handles light swimming and marine sports without battery changes. Buyers who require a dedicated dive model with screw-down crown or ISO-certified depth rating should consider other options.

Eco-Drive Caliber E111 movement never needs

Citizen's proprietary Eco-Drive Caliber E111 converts natural or artificial light into energy, eliminating battery replacements entirely. This single feature decides whether the watch matches a buyer who values set-and-forget convenience over manual winding or periodic battery service.

Questions about this item

Will the Eco-Drive Caliber E111 movement need a battery change or capacitor service later?

The E111 movement is light-powered and designed to run without battery replacements; only the strap or crystal may need attention after years of wear.

What stops the watch first during continuous daily wear — power reserve or water-resistance seals?

The movement stores enough energy to run for months in darkness, so the 100 m water-resistance seals are the first items that can degrade and require resealing.

How warm does the case get and does the movement make any noise when worn all day?

The analog E111 movement is silent and the stainless steel case stays at skin temperature during normal all-day wear.
