Reviews

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

Aigi Watches Arctic Tide

Owners report the Aigi Arctic Tide's dial markers catch the light similarly to Grand Seiko dials, and one user noted a preference for its movement over an alternative. Some owners consider the 40mm case size comfortable, while others found a 43mm variant chunky. One owner received their watch with a Miyota 9015 movement upgrade, and another experienced issues with lume and alignment on their initial unit, receiving a replacement. On balance, owners view the Aigi Arctic Tide as a decent value at its Kickstarter price, with good on-paper specifications, though concerns exist regarding the brand's newness and potential for it to be a catalogue watch.

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.
