Citizen Eco-Drive OnevsWolbrook Skindiver Automatic

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 widely praise the Wolbrook Skindiver Automatic 38mm for its vintage-inspired design, compact 38mm size, and tool-like aesthetic, offering good value for its price. The watch features ridiculously bright and long-lasting lume, a clean dial, and a Miyota 9039 no-date movement. Some owners find the push-pull crown a drawback, while others note the clasp and some bracelet links can feel sharp. Opinions are split on the bracelet design, with some finding it confusing and others praising its articulation and micro-adjustments. One owner found the 40mm case felt larger than expected. Overall, owners rate the Wolbrook Skindiver Automatic 38mm highly for its vintage aesthetic and tool-watch appeal at a reasonable price.
