What people say

Owners + reviewers, side by side

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

Straton Curve Chrono MKII

The watch offers a retro motorsport aesthetic with a quality finish and well-chosen movements at an affordable price. Reviewers did not agree on any specific weaknesses.

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.
