What people say

Owners + reviewers, side by side

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

Schofield B3

The Schofield B3 is widely praised for its exceptional packaging and the unique character of its pre-patinated bronze case, which reviewers found imbues the watch with warmth. Owners highlight its comfortable wearability, attributing it to a flat case back that mitigates its 44mm size, and the striking petrol blue and gold dial. One owner notes the winding action of the steel crown as a minor point of contention. The value proposition is debated within the community, with some questioning the inclusion of a Seiko NH34 movement at its price point. Overall, owners and reviewers rate the Schofield B3 highly for its distinctive case patina and thoughtful design details.

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.
