Citizen Chronograph Blue Dial Eco-Drive CA4505-80M 100M Watch

Chronograph with Eco-Drive movement

The Citizen CA4505-80M is a men's chronograph powered by the B620 solar movement, converting any light source into energy to run without battery changes. A stainless steel case and bracelet with a blue dial and mineral crystal give it a professional look suited for daily wear or formal occasions. Water resistance to 100 metres supports swimming and snorkelling. The watch fits wrists that accept a 44.00 mm case thickness and a deployment clasp.

Sustained daily performance

Solar charging keeps the movement running continuously under normal indoor and outdoor light, removing the stop-start cycle of battery-powered quartz. The chronograph function operates reliably for repeated timing tasks, while the date display advances automatically. Fixed bezel and mineral crystal maintain legibility and protection through regular exposure to moisture, sweat and minor impacts without degradation of function.

Installation and common issues

The bracelet requires link removal or addition for a precise fit, a task best handled by a watchmaker or jeweller to avoid scratched lugs or stripped pins. Deployment clasp alignment must be checked after sizing so the safety latch engages fully. Mineral crystal resists daily knocks but can shatter under sharp impact; owners expecting sapphire hardness should note the difference. Crown must be pushed fully home after setting to preserve 100m water resistance.
