What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Eco-Drive One

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.

William Wood Beacon

The William Wood Beacon is praised for its bold flavors, particularly its prominent oak and rye influence, with tasting notes of candied orange peel, dried apricots, and baking spices, and a long, full finish. Some find its oak-forward profile overwhelming and its MSRP of $300 unreasonable. Overall, owners rate the William Wood Beacon highly for its bold flavors and character, with one owner awarding it a score of 9.4/10.
