Citizen AW1780-17L Eco-Drive 40mm Men's Blue Leather Watch

A Citizen AW1780-17L with Eco-Drive solar power and a blue dial

Overview

With the AW1780-17L, Citizen focuses on solar power: this men's watch charges in the light and does not require a battery. It combines a stainless steel case, 40 mm in diameter, with a leather strap. On a blue background, Roman numerals and indices provide the time markers. An Eco-Drive can remain exposed to light without risk of overcharging.

Case

The AW1780-17L houses its movement in a stainless steel case, which measures 40 mm in diameter and 8.99 mm thick. The water resistance reaches 30 m (3 ATM): a shower or a splash is not a problem, but the pool and the sea are excluded. A mineral crystal covers the dial; a fixed bezel surrounds it.

Movement

Under the dial, the J810-00M caliber receives its energy from a photovoltaic cell and stores it in a rechargeable battery. Several months of power reserve: that is what a full charge provides when the light disappears. The low charge warning is triggered before the watch stops. In addition to the time, the dial displays the date.

Strap

The case is mounted on a leather strap. When fully assembled, the weight reaches 48 g. The purchase is covered by a two-year warranty.

Supplied with: Storage box, presentation pad, user manual.
