What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Grand Seiko SBGH368

The Grand Seiko SBGH368 is praised for its aggressive styling and textured copper-pink dial, inspired by cherry blossoms. Reviewers highlight its 38mm 18k rose gold 62GS case, featuring Zaratsu polishing, as a standout element. The watch is powered by the Hi-Beat Caliber 9S85 movement, which is regulated to -3/+5 seconds per day and offers a 55-hour power reserve. It also features 100m water resistance. One reviewer notes that the brown crocodile strap, while handsome, would ideally be replaced with a water-resistant option given the watch's 100m water resistance. There is also a question raised about whether a movement with a longer power reserve could have been utilized. The Grand Seiko SBGH368 retails for $31,200. Overall, reviewers consider the Grand Seiko SBGH368 a favorite gold-cased Grand Seiko, with its rose gold case and cherry blossom dial described as an exceptional combination.

Yema Superman Steel CMM.10

Owners widely praise the Yema Superman Steel CMM.10 for its refined casework, including polished lug bevels and an elegant crown guard, and its comfortable 39mm x 10.5mm dimensions. The glossy black lacquer dial and bezel insert are noted for adding depth, and the in-house CMM.10 movement is reported to be accurate, with one owner observing a loss of only 2 seconds over 2 days. The scales bracelet is described as gorgeous and nearly invisible on the wrist, though some find its polished center links too flashy. One reviewer flagged the signature bezel lock mechanism as flimsy and inconvenient. The CMM.10 automatic movement offers a 70-hour power reserve and is regulated to within +5/-3 seconds per day. On balance, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.

From video reviewers

The Yema Steel features an in-house movement with a micro-rotor, one of the most beautiful at this price point. The watch's clasp feels a bit thin, which is a notable drawback. Reviewers disagree on the movement's power reserve, with one reviewer noting a 42-hour reserve and the other not mentioning power reserve at all.
