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 a case thickness of 2.98mm, making it the world's thinnest light-powered watch. Owners and reviewers alike praise its "wow factor," describing it as "svelte" and "beautiful" with a titanium case and bracelet that feels exceptionally light on the wrist. The Eco-Drive quartz movement offers a power reserve of up to 100 days, and its miniaturization is considered impressive. However, the price is noted as a significant barrier for some, and one owner finds its aesthetic too plain or dated. Servicing is restricted to authorized centers due to proprietary construction. Overall, owners and reviewers rate the Citizen Eco-Drive One highly for its extreme thinness and lightweight titanium construction.

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.
