Reviews

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

Shiro Kara Daibāzu: Hulk SUB

Owners widely praise the Shiro Kara Daibāzu: Hulk SUB for its dial printing, insert, and rehaut finishing, with one owner noting good timegrapher numbers. One owner found the watch waterproof after five days, and another reported it was still running on day six. Some owners note a slightly off-centered 12 marker, and one felt the crystal was not the best, though still looked great. One owner expressed dissatisfaction with the bracelet quality. Overall, owners rate the Shiro Kara Daibāzu: Hulk SUB highly for its dial, insert, and rehaut finishing, with some noting good water resistance.

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.
