Citizen Eco-Drive OnevsVario NAVI Single Hand Compass

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 praise the Vario NAVI Single Hand Compass for its unique single-hand design and understated nautical theme, finding it reflects their personal style. The watch is a 38mm vintage-inspired timepiece with 100m water resistance. A reviewer notes the Miyota 8s25 automatic movement has a 40-hour power reserve and its unidirectional winding rotor may wobble. Overall, owners appreciate the Vario NAVI Single Hand Compass for its refreshingly different take and casual time-telling dial.
