Citizen Eco-Drive OnevsMarathon Jeep Willys SSGPQ

The Citizen Eco-Drive One is widely celebrated for its groundbreaking thinness, with multiple sources confirming a case thickness of 2.98mm, making it the world's thinnest light-powered watch. Owners and reviewers alike praise its "wow factor," describing it as "svelte" and "beautiful" with a titanium case and bracelet that feels exceptionally light on the wrist. The Eco-Drive quartz movement offers a power reserve of up to 100 days, and its miniaturization is considered impressive. However, the price is noted as a significant barrier for some, and one owner finds its aesthetic too plain or dated. Servicing is restricted to authorized centers due to proprietary construction. Overall, owners and reviewers rate the Citizen Eco-Drive One highly for its extreme thinness and lightweight titanium construction.

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.
