Citizen Eco-Drive OnevsVenezianico Nereide Acquaforte

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 Venezianico Nereide's striking dial design and overall finishing, with many finding its appearance and feel superior in person. The bracelet is noted for its comfort and quality, and the watch is considered suitable for daily wear. Some owners find the case a bit thick for wear under a cuff. The movement is a point of discussion, with one owner preferring a thinner, more accurate caliber over the NH45a, while another review highlights the reliable Sellita SW200-1. The watch is regarded as a good value mechanical diver-style timepiece, featuring a handsome design with a decorative tungsten bezel and aventurine dial, though the stock rubber strap can be stiff. Overall, owners rate the Venezianico Nereide highly for its exceptional dial and finishing at its price point.
