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

Owners widely praise the Longines SPIRIT 37mm for its excellent value, refined finishing, and vintage-inspired design, with many highlighting its applied Arabic numerals and appealing dials. The smooth winding action and technical capabilities like the 72-hour power reserve and silicon hairspring are also noted strengths. However, some owners find the bracelet to be "tinny" and light, and the lack of tool-less micro-adjustments on the bracelet is a recurring point of dissatisfaction. The date window at 3 o'clock is polarizing, with some disliking its placement and color, and the lugs are perceived by some as long for the case size. One owner expressed concern about the serviceability of the exclusive L888.4 movement. Overall, owners and reviewers consider the Longines SPIRIT a highly competent and well-executed watch for its price, with its design and finishing being the primary draws.

From video reviewers

The watch features a COSC-certified automatic movement. Reviewers noted the excellent finishing on the case and applied numerals. The lume brightness was cited as a weakness.

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.
