Citizen Eco-Drive OnevsTissot PR 100 Sport Chic

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 Tissot PR 100 Sport Chic for its robust build, 100m water resistance, and sapphire crystal, with one owner highlighting the 36mm size and mother-of-pearl dial as appealing. The ETA quartz movement is considered trustworthy, and the watch is seen as a versatile option for everyday wear. However, some find the quartz movement less engaging, and one owner expressed concern about the durability of rose gold PVD coating over time. Overall, owners and reviewers consider the Tissot PR 100 Sport Chic a solid, value-driven quartz watch suitable for casual and sports wear.
