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

Owners widely praise the Longines Spirit Pilot for its exceptional finishing, featuring sharp edges and crisp transitions, and its improved wearability thanks to a reduced 39mm case size and 47.2mm lug-to-lug distance. Reviewers and owners alike highlight the clean, balanced dial with gilt-toned accents that play with light, and its excellent legibility and lume. The L888.4 automatic movement is noted for its 72-hour power reserve and COSC certification. Some owners feel the Longines Spirit Pilot wears larger than its 39mm diameter and express disappointment over the removal of the five stars from the dial, while others find its bracelet endlinks long and lament the lack of quick-release. One owner voices concern over the serviceability of exclusive movements. Overall, owners rate the Longines Spirit Pilot highly for its modern icon status and value, feeling it wears more expensively than its price point suggests.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
