Citizen Eco-Drive OnevsPhoibos Voyager

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 Phoibos Voyager for its attractive MOP dial and good overall finishing, along with its fun octopus logo. However, reviewers and owners alike note that the red lettering on the red date wheel is illegible, and one owner reports the 13.5mm thick case can be prone to accidental knocks. On balance, owners rate the Phoibos Voyager highly for its attractive dial and finishing at the price point.
