Citizen Eco-Drive OnevsOmega Seamaster Quartz ST

The Citizen Eco-Drive One is widely praised for its status as the world's thinnest light-powered watch, with sources consistently citing its remarkable 2.98mm case thickness and 1mm movement. Owners and reviewers highlight its "wow factor," good build quality, and light weight due to titanium construction, with finishing compared favorably to higher-end models. The watch features a synthetic sapphire dial and a cermet bezel for protection. Some users note the absence of a seconds hand and basic functionality due to the miniaturized movement. While one source mentions a 100-day power reserve, another states it can run for 12 months on a full charge. The price is noted as $3,500 to $5,000, considered reasonable by some for the technology. However, its high price and splash-resistant water rating are seen as drawbacks by some, and a few find its aesthetic too plain, preferring other Citizen models.

Owners widely praise the Omega Seamaster Quartz ST 196.0082 for its reliability and accuracy, with one owner reporting it keeps time within 1-2 seconds per month. Some owners find the design difficult to read, and the bracelet finish has been criticized for incorrect brushing and polishing. One owner noted a temporary second-hand failure that resolved itself, while another experienced a costly movement replacement due to a battery leak. The helium escape valve is considered by some to be both ugly and unnecessary. On balance, owners value the Omega Seamaster Quartz ST 196.0082 for its dependable performance, though concerns exist regarding potential servicing costs and clasp durability.
