Citizen Eco-Drive OnevsCincinnati Watch Company Union Terminal Mechanical Watch, Gold (PVD)

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.

The Cincinnati Watch Company Union Terminal Mechanical Watch, Gold (PVD) is praised for its Art Deco design and hometown symbolism, echoing the historic Union Terminal clock with striking colors. Owners highlight its 36mm size and 10.2mm thickness as comfortable for dressier occasions, particularly on a leather strap. The Sellita SW300 movement is noted as offering excellent value under $1000, though some find the lack of a screw-down crown and date function limits its everyday versatility. Overall, owners rate the Cincinnati Watch Company Union Terminal Mechanical Watch, Gold (PVD) highly for its iconic design and sentimental value at its price point.
