Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Citizen Eco-Drive One is widely celebrated for its groundbreaking thinness, with multiple sources confirming its status as the world's thinnest light-powered watch, measuring between 2.98mm and 3.5mm. Owners and reviewers alike praise its exceptional lightness, titanium construction, and good build quality that avoids feeling flimsy, noting its "wow factor" and superb finishing. The watch features a proprietary, ultra-thin Eco-Drive quartz movement and a synthetic sapphire dial, with some models offering up to 12 months of power reserve. However, its high price, ranging from $3,500 to $5,000, is a significant drawback for some, and its aesthetic is considered too plain or dated by a minority who prefer other Citizen models. The Citizen Eco-Drive One is also noted for lacking a seconds hand and having only splash-resistant water protection.
Owners widely praise the KUOE ROYAL SMITH 90-006 for its visual appeal and sapphire crystal with AR coating. The watch functions correctly and keeps time at approximately +5 seconds per day on the wrist, powered by a Miyota 9039 movement. On balance, owners value the watch's aesthetics and specifications, though some question its overall value proposition.
The watch's unique blend of modern and retro elements is a notable strength, with a textured ivory waffle dial and Breguet numerals giving it the look of a vintage watch from the 1950s and 1960s. A potential drawback is the ~$770 USD price point, which is significant for a microbrand. Reviewers disagree on the movement's accuracy, with one reviewer noting it is noisy and another describing it as a "Japanese-manufactured high beat premium automatic movement".
