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.

Spinnaker Tesei Mille Metri GMT

The Spinnaker Fleuss Midnight Black features a reliable and accurate Japanese TMI NH35 Automatic Movement with 3 Hands and Date. A potential drawback is the watch's relatively low 15 ATM water-resistance rating compared to other watches in its class. Reviewers disagree on the watch's suitability for larger wrists, with one reviewer noting a 43mm diameter and 51mm lug-to-lug fit, while the other mentions a 51mm lug-to-lug measurement.
