Citizen Eco-Drive OnevsPagani Design PD-1766

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 Pagani Design PD-1766 for its attractive dial options, comfortable wearability, and light weight. Some owners find the textured green and blue dials appealing, with one owner noting it's among their most worn watches and would buy more colors. However, the bracelet is frequently criticized as cheap-looking and poorly constructed, with one owner calling it "brutal" and "crap," and the included tool is too large for the faux screw pins. Concerns are also raised about a lack of a running second hand, a potentially reflective crystal, and misaligned indices or bezels on some examples. On balance, owners appreciate the Pagani Design PD-1766 for its comfortable fit and attractive dial at its price point, despite significant criticism of the bracelet quality.
