Citizen Eco-Drive OnevsBrew Retrograph

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 Brew Retrograph is widely praised for its unique 1970s "TV Dial" aesthetic, thin profile, and comfortable wearability, with owners appreciating its well-finished rectangular case featuring alternating polishing and brushing, and its sunburst dials with contrasting matte subdials. Reviewers and owners consistently highlight the Seiko VK64 meca-quartz movement for its solid performance, instantaneous chronograph reset with good tactile feel, and quartz accuracy, all at an affordable price point. Some owners note the lack of a running second hand and that the date change is not instant, while one owner found the strap needed improvement. Overall, owners and reviewers rate the Brew Retrograph highly for its distinctive design and excellent value, particularly praising its comfortable wearability and the satisfying meca-quartz chronograph function.
