The numbers, the dial colors, the calibers — laid out so you can stop flipping between tabs.
Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Grand Seiko STGF359 for its elegant pairing with an engagement ring. Some owners find the 29mm case size too small for a man's wrist, while others suggest it can be worn by men with smaller wrists, recommending an in-person try-on. One owner notes potential date wheel misalignment requiring servicing. The bracelet has a maximum perimeter of 185mm, with extra links available. On balance, owners value the Grand Seiko STGF359 for its elegant aesthetic, though its small size is a point of consideration.
The Grand Seiko STGF359 features a 9F quartz movement with exceptional accuracy, deviating by only +/−10 seconds per year. A drawback of the watch is its 40mm case size, which may be a concern for those with smaller wrists. Reviewers disagree on the type of movement, with one praising the 9F quartz and the other highlighting the spring drive movement.
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.
