Citizen Eco-Drive OnevsDan Henry 1970

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 Dan Henry 1970 for its striking looks, particularly the art deco hands and fantastic crystal. The 44mm size is noted as a drawback for wrists under 7 inches, and one owner reported strap change marks inside the lugs and a small mark on the clasp. The watch features a 41-hour power reserve and 200-meter water resistance. Overall, owners rate the Dan Henry 1970 highly for its distinctive vintage-inspired design and value at $295.
