Citizen Men’s Eco-Drive Sport Casual Brycen Chronograph

Product Overview

The Citizen Men’s Eco-Drive Sport Casual Brycen Chronograph Watch blends modern functionality with rugged durability, making it a versatile companion for active lifestyles. Part of the Weekender Brycen collection, this timepiece is engineered for men who appreciate precision, comfort, and enduring style. Its standout feature is the use of Super Titanium™—a material five times harder and 40% lighter than traditional stainless steel—offering exceptional resilience without the added weight. Whether you’re navigating a busy workday, hitting the gym, or enjoying outdoor adventures, this watch delivers reliable performance in a sleek two-tone design.

At the heart of the Brycen is Citizen’s award-winning Eco-Drive technology, which converts any light source—natural or artificial—into energy to power the watch. This eliminates the need for battery replacements, ensuring continuous operation as long as the watch is exposed to light regularly. Paired with a suite of practical functions, including a chronograph, perpetual calendar, and alarm, the Brycen is built to support both daily routines and active pursuits.

Key Features

• Super Titanium™ Case & Bracelet: Crafted from solid titanium and enhanced with Citizen’s proprietary Duratect surface-hardening technology, this material resists scratches, maintains its finish, and remains remarkably lightweight. It’s naturally hypoallergenic, making it ideal for sensitive skin, and highly resistant to corrosion from saltwater and moisture.
• Eco-Drive Technology: Powered entirely by light, this watch never requires a battery. Regular exposure to indoor or outdoor light keeps it running indefinitely, offering both convenience and environmental sustainability.
