Reviews

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

Knot Watches AT-38

Knot Watches Knot AT-38 owners praise its 38mm case size, 10mm case height, and 45mm lug-to-lug as fitting perfectly on smaller wrists, with one owner finding it surprisingly light and comfortable. The multi-layered Urushi lacquer dial, featuring gold applied via scraping, is described as stunning in person and a key aesthetic appeal, while the Miyota 9015 movement is considered good. Some owners note that Knot straps are too short for larger wrists and the strap width is slightly smaller than standard, preventing the use of preferred aftermarket options. On balance, owners rate the Knot Watches Knot AT-38 highly for its comfortable dimensions and the striking dial design at its price point.

Seiko King Seiko KSK

Owners widely praise the Seiko King Seiko KSK's confident, harmonious mid-century design and sharply faceted case with Zaratsu polished surfaces. Some owners note the caseback and clasp screws can be misaligned, though others dismiss these as minor issues. The watch is described as a daytime-only piece due to a lack of lume, and the hidden butterfly clasp is considered unintuitive by one reviewer. Accuracy is reported as +25 to -15 seconds per day, which some find lacking for the price. Overall, owners and reviewers appreciate the King Seiko KSK's design and finishing but express concerns regarding the movement and accuracy at its price point.

From video reviewers

The Zaratsu polished facets and indexes are a strong point, replicating the original design. Reviewers questioned the high price point of the reissue.
