Citizen Eco-Drive OnevsVenezianico Nereide GMT Grand Tour

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.

Owners widely praise the Venezianico Nereide GMT Grand Tour for its beautiful and colorful design, refined muted blue dial, and Italian-made 39mm case with sapphire crystal and AR coating. The bracelet is frequently noted as feeling great on the wrist, and one owner reports excellent accuracy at +-2 seconds per day. Some owners appreciate the dress-casual sport watch feel and the rose gold mirrored bezel portion, while others find the optical glass bezel preferable for reduced glare. However, some find the watch large, and one owner experienced the butterfly clasp opening while swimming. The price is considered steep by some for a Miyota GMT, though others feel it is justified by the improved case finishing and solid feel, especially compared to other movements. The unidirectional 120-click bezel is noted as essentially a diver bezel with a different insert.
