Citizen Eco-Drive OnevsFarer GMT

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 Farer GMT Automatic is praised for its vibrant, legible sunburst dial and well-proportioned 39.5mm x 10mm case. Reviewers note the ETA 2893-2 movement as a good choice with hacking seconds and a 42-hour power reserve. The bronze crown, intended to develop a patina, is flagged as a potentially unpopular design element that some feel looks unfinished or out of place. Prices range from $1,425 to $2,150 AUD. Overall, reviewers find the Farer GMT Automatic offers good value for a GMT watch in its price segment, with the dial and case proportions being key strengths.
