Citizen Eco-Drive OnevsVaer DS4 Meridian Solar

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.

Owners widely praise the Vaer DS4 Meridian Solar for its exceptional value, solar-powered functionality, and attractive sunburst dials, with one owner reporting perfect timekeeping at 0 seconds per day. Reviewers and owners alike note the sapphire crystal with AR coating and 200m water resistance as key strengths. However, the premium steel bracelet is criticized by some for a jangly feel and sharp edges, and the crown's sharp edges can dig into the wrist. The second hand's alignment between markers is reported as slightly off by multiple owners, a trait Vaer attributes to the watch's price point. Overall, owners and reviewers rate the Vaer DS4 Meridian Solar highly for its excellent value and robust specifications, particularly its solar movement and durable crystal.
