Grand Seiko SLGH017vsYema YEMA x Silberstein Marine 2 CMM.20 Limited Edition

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.

The YEMA x Silberstein Marine 2 CMM.20 Limited Edition is noted for its slim 39mm case and in-house CMM.20 micro-rotor movement, offering 300 meters of water resistance and a 70-hour power reserve. Reviewers highlight the watch's thin profile and flowing case design, as well as its black lacquered enamel dial. However, the bezel's lack of numbers is considered a practical drawback, and one reviewer noted the audible spin of the micro-rotor, which was unexpected given the €1,990 price for the 200-piece limited edition. The included leather strap is also seen as less suited for the watch's dive capabilities. Overall, reviewers appreciate the YEMA x Silberstein Marine 2 CMM.20 Limited Edition for its slim design and in-house movement, though practical considerations regarding the bezel and strap are noted.
