Citizen Eco-Drive OnevsMarathon Jeep Willys SSGPQ

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 Marathon Jeep Willys SSGPQ is a vintage-inspired sports watch with a handsome dial honoring military heritage and a unique case shape. It features a 41mm stainless steel case with a matte parkerized finish, a sapphire crystal, and a MaraGlo luminous dial, powered by an ETA F06.402 quartz movement. Reviewers note that its longer lugs may extend past smaller wrists and the included leather strap is fragile. The Marathon Jeep Willys SSGPQ is available for $500 to $650 USD. On balance, reviewers find the Marathon Jeep Willys SSGPQ to be a good value, particularly for vintage Jeep enthusiasts, due to its design and heritage-inspired dial.
