Citizen Eco-Drive OnevsMarathon Jeep Rubicon GSAR

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 Rubicon GSAR is widely praised as a rugged, high-quality tool watch that successfully blends Jeep branding with Marathon's functional heritage, featuring a unique dial with tritium illumination and an automatic Sellita SW200-1 movement. Owners appreciate its satisfying bezel action and durable build, making it a reliable daily wear that pairs well with Jeep's rugged image. However, some find the Jeep logo to be corporate and out of place with Marathon's austere design ethos, while one owner notes that second-hand examples can show wear on the bezel. The watch is priced at $1,500 USD. Overall, owners and reviewers rate the Marathon Jeep Rubicon GSAR highly for its robust construction and distinctive tritium lume, which are considered its strongest assets.
