Citizen Zenshin CA4690-51A Men’s 41 mm Super Titanium Eco-Drive Chronograph Watch, White Dial

Battery-free Eco-Drive, 41 mm case: the Citizen CA4690-51A

Overview

A solar men's watch, the Citizen CA4690-51A does not need a battery: its solar cell captures any light source. It measures 41 mm in diameter and features a titanium (Super Titanium) case and bracelet. The hour markers serve as reference points on the white dial. No winding, no battery: only light keeps it running. The titanium makes the watch significantly lighter than steel.

Case

Crafted from titanium (Super Titanium), the case sits on the wrist with a 41 mm diameter and 11.68 mm thickness. A sapphire crystal covers the dial; a fixed bezel frames it; at the back, a solid case back protects the movement. The stated water resistance is 100 m (10 ATM): the watch follows its wearer to the pool for swimming or free diving, but not with a scuba tank.

Movement

The B620-00M caliber belongs to Citizen's Eco-Drive family, which works by converting light received by the dial into electrical energy. When light has been lacking for too long, a low charge warning lets you know. Without light, the watch can still run for several months if it has been fully charged. The dial displays the date in addition to the time. It also features a 24-hour display and a chronograph.

Bracelet

The case is paired with a titanium bracelet with a deployant clasp. When fully assembled, the total weight is 97 g. This watch comes with a two-year warranty.

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