Citizen Eco-Drive OnevsMaen Manhattan 37 Worn & Wound Edition

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 report the Maen Manhattan 37 Worn & Wound Edition offers exceptional build quality for its price point, often seen as a step above other microbrands in the $500 range. Reviewers highlight its pared-down, dressy design with fumé dials and stripped-down indices, noting the bracelet finishing appears strong for its $899 cost. The use of a Sellita SW 200-1 movement is considered a fine compromise for affordability, and its 9.3mm thickness is a notable wearability feature. Overall, owners and reviewers rate the Maen Manhattan 37 Worn & Wound Edition highly for its superior finishing and design at its price.
