What people say

Owners + reviewers, side by side

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

Longines SPIRIT PILOT FLYBACK

The Longines Spirit Pilot Flyback is widely praised for its refined 39.5mm case size, improved wearability, and clean dial design, incorporating enthusiast feedback by removing the five stars and date. Reviewers and owners consistently highlight its exceptional finishing, well-acting ceramic bezel, and the value it offers. The manual-winding L792.4 column-wheel chronograph movement is COSC-certified and offers a power reserve of approximately 68 to 72 hours. Some owners expressed disappointment with the removal of the five stars from the dial, and one reviewer noted that some numerals are partially cut off by the subdials. The watch is priced around $5,350 to $5,550 USD. Overall, owners and reviewers rate the Longines Spirit Pilot Flyback highly for its improved dimensions, finishing, and value proposition.

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.
