What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Thinline Small Second Quartz

Owners widely praise the Hamilton Jazzmaster Thinline Small Second Quartz for its excellent value around $300, thin profile at 7mm to 8.4mm, and clean dial design with superb applied hour numerals and dauphine hands. One owner finds its champagne dial particularly upscale. However, the lume is considered terrible, barely lasting a few minutes, and the crown is noted as very small and difficult to manipulate. On balance, owners rate the Hamilton Jazzmaster Thinline Small Second Quartz highly for its thinness and clean dial design at the price.

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.
