Citizen Eco-Drive OnevsPagani Design PD-YS020

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 report issues with the Pagani Design PD-YS020's integrated bracelet, describing it as stiff, ill-fitting, and difficult to resize due to stiff pins and a lack of half links, leading to discomfort and a "bangle-like" feel for some. The seconds hand alignment and dial brushing are also noted as imperfect. However, some owners find the watch beautiful and thin, with the silver dial offering surprising light play, and consider it a well-done homage for its price. On balance, owners find the Pagani Design PD-YS020's bracelet design and sizing challenges to be significant drawbacks that detract from its wearability.
