Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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 Vaer C1 Ceremony Quartz for its excellent finishing, which some consider the best within the brand's offerings. Its 36mm case is frequently highlighted as offering perfect dimensions and a dress watch sweet spot, contributing to a thinner profile due to its quartz movement. The dial work is described as phenomenal, and the watch is lauded for its clarity and accuracy, making it a practical choice. One owner notes the premium Jubilee bracelet is included, while another mentions availability with a Horween leather strap. The price is considered a steal by one owner. However, one owner expresses a desire for a sweeping seconds hand, finding the standard quartz "tick" less stately. Overall, owners rate the Vaer C1 Ceremony Quartz highly for its exceptional finishing and ideal 36mm sizing at the price.
