What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Eco-Drive One

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.

Hamilton American Classic Hamilton Necklace

Owners widely praise the American Classic Hamilton Necklace for its elegant, dainty feel and the compliments it garners, with one owner selecting it for its American spirit, class, and budget-friendliness. The silver dial with gold hands and markings, and the Art Deco/Brutalist engraved lid are noted highlights. Some find the small size difficult to read, and one owner reports the strap is too short. Overall, owners rate the American Classic Hamilton Necklace highly for its elegant feel and attractive design details at an accessible price point.
