Citizen Eco-Drive OnevsTissot PRX

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 Tissot PRX is widely praised for its excellent case and bracelet finishing, offering remarkable value and a luxurious feel that belies its price point. Owners and reviewers consistently highlight its comfortable, thin profile and integrated bracelet design. The dial pattern is noted for its retro, 1980s aesthetic, and the reliable automatic movement contributes to its appeal as a strong contender for a first mechanical watch. However, some owners point out a lack of micro-adjustment on the bracelet clasp, and one reviewer noted issues with quality control on a chronograph model, including a malfunctioning hand and dust on the dial. The sapphire crystal's lack of AR-coating and the shininess of the hour and minute hands are also mentioned as minor drawbacks. On balance, owners and reviewers rate the Tissot PRX highly for its exceptional finishing and value proposition.
