What people say

Owners + reviewers, side by side

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

Airain Watches Type 20

Owners widely praise the Airain Watches Type 20 for its beautiful and faithful recreation of a classic model, highlighting its easily wearable 39mm case sizing and the pleasure of its manual winding movement. Reviewers note the pleasing "old radium" lume and the vintage military watch experience offered by modern construction. Some owners find the design timeless and clean, with one owner calling it "just perfect." However, reviewers point out that the vintage-style sapphire crystal can add glare, and the case is still considered a bit thick despite the manual movement. Strap hardware required swapping between included straps for one reviewer. One owner noted a small scratch on the crystal near the 12-hour mark. The movement's appearance is considered less attractive than many hand-wound chronographs by one reviewer. On balance, owners and reviewers rate the Airain Watches Type 20 highly for its faithful vintage design and enjoyable manual winding action.

Massena LAB Geometer

Massena LAB is lauded for its vintage-inspired designs, with reviewers highlighting the attractive sector dial and glossy black dial with gilt printing. The manual-winding SW510 Elaboré movement is noted, and the 39mm case is described as polished stainless steel. Some find the minute and hour hands difficult to distinguish, and one reviewer criticized the dial for only displaying Massena's name. The price points mentioned range from $5,995 to $8,675. Overall, reviewers rate Massena LAB highly for its vintage aesthetics and value, particularly noting the striking dials and modern horological touches.
