Grand Seiko SBGH347vsYema Superman Slim CMM.20

The Grand Seiko SBGH347 is lauded for its refined 37mm Ever-Brilliant Steel case, impressive Zaratsu polishing, and classy ice-blue dial inspired by frozen waterfalls. Its Hi-Beat 9S85 movement is a significant draw, and the framed date window is preferred over a cyclops. Reviewers note the bracelet lacks micro-adjustment or a quick-change system, and some wished the 13.3mm thickness was slightly thinner on the compact case. Overall, reviewers praise the Grand Seiko SBGH347 for its elevated finish and value, with the Hi-Beat movement being a significant draw.

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
