Omega Seamaster Diver 300M QuartzvsYema Superman Slim CMM.20

Owners widely praise the Omega Seamaster Diver 300M Quartz for its excellent timekeeping and comfortable wear, with one owner noting their 2010 model passed a recent pressure test. The watch is considered a good buy between $1000-$1200, and its original Omega design is highly appreciated, with some owners calling it one of their favorite watches ever made. One owner reports their 2009 model required only a battery change, water resistance restoration, and case refinishing for $200, while another notes finding an original bracelet can be a challenge. The quartz model is sought after partly due to its appearance in the Goldeneye film, and its stated accuracy is +/- 15 seconds per month. Overall, owners rate the Omega Seamaster Diver 300M Quartz highly for its robust performance and enduring design as an introduction to luxury watches.

Owners widely praise the Yema Superman Slim CMM.20's appealing retro design, 39mm case, and the in-house CMM.20 micro-rotor movement, with some specifically noting the fish scale bracelet. Reviewers and owners alike mention the movement's design can lead to a "jittery" seconds hand, though Yema states this does not impact performance. Some owners question the $2500 MSRP, finding it overpriced, while others note initial stiffness in the bracelet that improves with wear. Finishing inconsistencies were noted on a prototype, and the stamped clasp on the bracelet is considered subpar by one reviewer. Overall, owners and reviewers find the Yema Superman Slim CMM.20 a compelling option for its vintage styling and unique micro-rotor movement, despite some concerns about its value proposition and minor execution details.
