What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Eco-Drive One

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.

Vaer Calendar Field

Owners widely praise the Vaer Calendar Field for its excellent value, citing its clean WWII-inspired dial, thin 8.5mm to 9.5mm case, sapphire crystal, and 100m water resistance. The dial and hand design are consistently highlighted as phenomenal, with case finishing described as next-level for the price, featuring nice brushing. Some owners note the second hand does not perfectly align with markers, and the stock silicone strap attracts lint. One owner found the lume only serviceable and wished the date window was brighter. On balance, owners rate the Vaer Calendar Field highly for its exceptional dial design and case finishing at its price point.
