What people say

Owners + reviewers, side by side

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

Sternglas Naos XL Automatik

Owners widely praise the Sternglas Naos XL Automatik as an amazing and best affordable automatic Bauhaus watch for its price. However, some owners find the 42mm case size too large, with one describing it as resembling a "flying saucer" on a 7.25-inch wrist, and another noting its unsuitability for a predominantly white dial. The Miyota movement is described as just okay. Overall, owners rate the Sternglas Naos XL Automatik highly for its value proposition as an affordable Bauhaus automatic.

Yema Superman Slim CMM.20

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.
