Citizen Eco-Drive OnevsVaer G2 Apocalypse GMT

The Citizen Eco-Drive One is widely celebrated for its groundbreaking thinness, with multiple sources confirming its status as the world's thinnest light-powered watch, measuring between 2.98mm and 3.5mm. Owners and reviewers alike praise its exceptional lightness, titanium construction, and good build quality that avoids feeling flimsy, noting its "wow factor" and superb finishing. The watch features a proprietary, ultra-thin Eco-Drive quartz movement and a synthetic sapphire dial, with some models offering up to 12 months of power reserve. However, its high price, ranging from $3,500 to $5,000, is a significant drawback for some, and its aesthetic is considered too plain or dated by a minority who prefer other Citizen models. The Citizen Eco-Drive One is also noted for lacking a seconds hand and having only splash-resistant water protection.

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.
