Citizen Eco-Drive OnevsVaer G2 Apocalypse GMT

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 praise the Vaer G2 Apocalypse GMT's well-executed proportions and smooth GMT bezel action. One owner reports quality control issues such as misaligned hands and dust under the crystal, attributing these to the sub-$500 price point. The watch features a caller-style quartz movement for quick-set date adjustment and its lume is functional, though noted as a step below other models. Overall, owners find the Vaer G2 Apocalypse GMT offers good value for its price, despite potential quality control concerns.
