Reviews

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

MKII Stingray II

The MKII Stingray II is widely praised for its utilitarian design, smooth bezel action, and excellent legibility with a matte dial and sword hands. Owners appreciate the wearable 40mm sandblasted case, though its 14.7mm thickness is noted as substantial for the size. Accuracy is a point of divergence, with one owner reporting degradation from +/- 15-30 seconds per day to -30-40 seconds per day, while another source does not specify accuracy. The 4:30 date window is a common point of contention among reviewers. Overall, owners and reviewers rate the MKII Stingray II highly for its robust design and legibility at the price.

Yema Navygraf Heritage

Owners widely praise the Yema Navygraf Heritage for its comfortable 39mm wearability and faithful reissue of a 1970s model, with craftsmanship often noted as better than expected. Some owners highlight its retro look, yellow hands for legibility, and unique case design. However, multiple owners report quality control issues, including bezel free play, misalignment, and crown seating problems. Accuracy figures vary, with one owner noting it runs at +10 to +15 seconds per day, while another regulated theirs after losing 30 seconds per day, though another owner states theirs is accurate. The bezel is described as super tight to turn by one owner, despite having precise 120 clicks. Overall, owners find the Yema Navygraf Heritage a good-looking and quirky watch with notable value for its design and build.

From video reviewers

The 39mm case size and comfortable wearability are consistently praised. The in-house MBP1000 movement is mentioned as a strength by multiple reviewers. Reviewers disagree on the movement's quality, with one suggesting it should not have passed quality control while others highlight it as a positive feature.
