Citizen Eco-Drive OnevsVaer D5 Pacific Anacapa Auto

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.

The Vaer D5 Pacific Anacapa Auto is widely praised for its 39mm case size and refined yet rugged case design, with owners noting it wears well and fits perfectly. Reviewers and owners alike highlight the colorful, multi-layer dial, with one specifically appreciating the matte green dial's accenting of other colors. The watch's American assembly is also a point of praise. One owner found the fit superior to a previous Seiko "Baby Hulk." A reviewer noted the bezel numerals lack lume, and the date wheel's three-orange-one-green pattern is described as peculiar. One owner also felt the minute markers seemed oddly placed. The Vaer D5 Pacific Anacapa Auto uses a Miyota 9015 automatic movement with a 42-hour power reserve and offers 200m water resistance. Overall, owners and reviewers rate the Vaer D5 Pacific Anacapa Auto highly for its wearability and dial design at the price point.
