What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Eco-Drive

Citizen Eco-Drive watches are widely praised for exceptional durability and reliability, with many owners reporting theirs lasting over a decade without issue and some even suggesting they are "Buy It For Life" (BIFL) models. Owners appreciate the ease of use and reliability of the solar-powered quartz movement, with one noting their watch was only off by 2 minutes after five years of disuse. Specific models are noted for their engineering marvels, such as the world's thinnest light-powered watch at 2.98mm thick, a 100-day power reserve, and materials like cermet bezels and titanium construction with sapphire crystals. However, a few users have experienced malfunctions, including one chronograph that stopped keeping time shortly after purchase, requiring a lengthy warranty repair. The battery can degrade and may need replacement after 20+ years, and owners suggest keeping the watch charged in light to prolong its life.

Zelos Swordfish Field 38

Owners widely praise the Zelos Swordfish Field 38 for its comfortable dimensions, noting they are acceptable both on paper and in practice. The Seiko NH35 movement is highlighted for its exceptionally smooth winding feel. On balance, owners rate the Zelos Swordfish Field 38 highly for its value and comfortable wearability.
