What people say

Owners + reviewers, side by side

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

Massena LAB Dato-Racer

Owners widely praise the Massena LAB Dato-Racer as an excellent everyday watch, appreciating its blend of 1970s-inspired aesthetics with modern dimensions. This model is a limited edition of 99 pieces. On balance, owners rate the Massena LAB Dato-Racer highly for its successful fusion of vintage design and contemporary wearability.

Yema Navygraf Heritage

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful 1970s reissue design, noting craftsmanship better than expected. Some owners report quality control issues including bezel free play and misalignment, while others find the bezel very tight to turn despite precise 120 clicks. The in-house MBP2000 movement is noted by some to be loud and run approximately +10 to +15 seconds per day. On balance, owners appreciate the Yema Navygraf Heritage for its retro aesthetic and comfortable sizing, with noted concerns around movement accuracy and bezel action.
