What people say

Owners + reviewers, side by side

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

AVI-8 Spitfire Smith Automatic

Owners praise the AVI-8 Spitfire Smith Automatic for its dial depth created by elevated numerals, a deeply signed buckle, and detailed case sides. The watch is also noted for being practically mark-free with no dings found, and comes with a barely worn brown leather AVI-8 OEM strap. On balance, owners rate the AVI-8 Spitfire Smith Automatic highly for its detailed finishing and pristine condition.

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.
