Citizen Eco-Drive OnevsanOrdain Model 1

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 and reviewers widely praise the anOrdain Model 1 for its exquisite vitreous enamel dial, noting its depth, unique light play, and custom typography. The watch is also commended for its comfortable wearability, elegant design, and appealing price point for its handmade processes, with an 800 vickers hardened case resisting scratches well. Some owners report the Sellita SW200-1 movement's rotor is noticeable and the watch lacks lume. Significant wait times, potentially exceeding two years, are a frequently cited drawback. On balance, owners and reviewers rate the anOrdain Model 1 highly for its exceptional enamel dial and handcrafted aesthetic at the price.
