Citizen Eco-Drive OnevsFears Brunswick 38 (Steel)

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.

The Fears Brunswick 38 (Steel) is widely praised for its elegant 38mm case size and striking dial finishes, with reviewers highlighting the hand-polished Polar White dial's art-deco numerals, the Silver Sector dial's Arabic numerals, and the Champagne dial's glass bead-blasted texture. Case finishing is consistently noted as well-executed with a mix of brushing and polishing. Ownership and reviews mention 100 meters of water resistance. Some owners question the $4,400 price point, with one suggesting the bracelet adds an unjustified cost. The watch utilizes a manually wound ETA 7001 movement with a 40-hour power reserve, which one reviewer found a bit dated and noted the lack of hacking seconds; another review noted a La Joux Perret D100 movement with a 50-hour power reserve, stating its finishing was appropriate for the $3,650 price point.
