What people say

Owners + reviewers, side by side

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

Vario 1918 Trench Brass

Owners widely praise the Vario 1918 Trench Brass for its attractive, precisely made dial and case, with the evolving brass patina noted as a positive feature. The bund strap is considered comfortable and well-fitting by some, though others find it stiff and short for larger wrists. The lume is considered poor. The Miyota 82s5 movement is described as adequate, with accuracy ranging from about -10 seconds per day to simply running slow. On balance, owners rate the Vario 1918 Trench Brass highly for its fantastic looks and the unique character of its brass case.

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.
