Citizen Men’s Eco-Drive Weekender Garrison Field Watch

Product Overview

The Citizen Men’s Eco-Drive Weekender Garrison Field Watch is a practical and stylish choice for men who appreciate everyday durability and sustainable design. Part of the Weekender Sport Casual collection, this watch combines classic field-watch elements with modern functionality, making it well-suited for daily wear, weekend trips, or casual outings. Its black-on-black aesthetic delivers a clean, understated look that transitions easily from relaxed weekends to semi-formal occasions. What truly sets this timepiece apart is Citizen’s Eco-Drive technology—innovative solar-powered movement that charges from any light source, whether natural or artificial. This eliminates the need for battery changes and supports long-term environmental responsibility, offering peace of mind for the eco-conscious wearer.

Key Features

• Eco-Drive Technology: Powered entirely by light, this watch never needs a battery replacement. The internal rechargeable cell captures energy from sunlight or indoor lighting, ensuring continuous operation with minimal maintenance. Simply exposing the watch to light for a few hours can keep it running for months, making it ideal for travelers, busy professionals, or anyone who values convenience and sustainability.
• Durable Stainless Steel Case: The 37mm round case is constructed from high-quality stainless steel with a sleek black finish. This material offers excellent scratch resistance and structural integrity, standing up to the demands of daily wear while maintaining a refined appearance.
• Comfortable Nylon Strap: The black nylon strap is lightweight, breathable, and designed for all-day comfort. Its military-inspired design nods to traditional field watches, while the flexible material ensures a secure fit without irritation, even during extended wear.
• Mineral Crystal Lens: The watch face is protected by scratch-resistant mineral crystal, providing clear visibility and reliable defense against minor impacts, dust, and everyday abrasions. This ensures the dial remains legible and pristine over time.
• Buckle Clasp: A traditional buckle closure secures the watch firmly to your wrist. It’s easy to adjust and adds a classic touch that complements the watch’s field-inspired design.
• Water Resistance to 50 Meters: With a water resistance rating of 0050M (50 meters), this watch can handle splashes, rain, handwashing, and brief immersion in water. It’s suitable for everyday activities like light swimming or walking in the rain, but not intended for diving, snorkeling, or high-impact water sports.
