Citizen Eco-Drive OnevsCitizen The Citizen Caliber A060

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 Citizen Caliber A060 is widely praised for its exceptionally light, scratch-resistant Duratect-coated titanium case with a gold hue, and its highly accurate solar quartz movement. Owners appreciate its understated style, engineering, and versatile 38mm size, with many finding it a beautiful, well-built GADA watch with fantastic lume. Accuracy figures vary among owners, with some reporting gains of around 7 seconds per year, exceeding the advertised ±5 seconds, while others note near-zero deviation. One owner is bothered by a date change occurring 14 minutes past the hour, speculating it could be a defect. Overall, owners and reviewers consider The Citizen Caliber A060 a great value, particularly for its solar power, perpetual calendar, and independent hour hand features.
