Astor + Banks Fortitude LitevsCitizen Eco-Drive One

The Astor + Banks Fortitude Lite is praised for its reduced 10.9mm thickness and redesigned lugs that turn down, along with the removal of the date complication. One owner finds the white dial Fortitude Lite a good watch but not worth $650, suggesting better value from other brands, while another simply states it looks better than a specific alternative. Overall, owners praise the Astor + Banks Fortitude Lite for its wearability due to its thinner case and redesigned lugs.

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.
