Citizen Eco-Drive OnevsYema Rallygraf Meca-Quartz

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 Yema Rallygraf Meca-Quartz for its heritage reissue design, small and thin case, and good looks for the price, with some noting exceptional build quality, tactile pushers, and a substantial feel. However, the quartz movement's ticking smoothness and the 24-hour subdial, which functions as an AM/PM indicator rather than a totalizer, are points of criticism for some, leading to perceptions of it being overpriced. Owners report mixed experiences with quality control, with some noting alignment issues, crooked indices, and dial rotation when pushers are depressed, while others report no such issues. On balance, owners appreciate the Yema Rallygraf Meca-Quartz for its distinctive vintage styling and wearability, despite some concerns regarding quality control and the functionality of its subdial.
