Reviews

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

Nezumi Studios Baleine

Owners widely praise the Nezumi Studios Baleine for its stylish design updates, comfortable 40mm case size, and the soft feel of its strap, with one owner noting its striking appearance garners significant attention. Reviewers highlight its exceptional value, with the automatic version priced competitively, and appreciate the coin-edged bezel action. The watch features a boxed sapphire crystal, signed crown, buckle, and case back, and a textured matte black dial with applied numerals filled with warm-toned lume. Accuracy figures for the Miyota 9039 movement are stated as -10/+30 seconds per day, though actual performance is expected to be better, with one owner reporting initial fast running that settled. Some owners find the 40mm size ideal, while one wished for a smaller case. The gold DLC coating is a matter of personal preference, though it is acknowledged to be eye-catching. The included leather strap did not hold up well to sunscreen for one owner.

From video reviewers

The cohesive, original vintage-inspired design is the primary strength. Lume performance is a weakness.

Second Hour Shoal Deep

The Second Hour Shoal Deep — Second Hour is praised for its value, dynamic orange dial, and beads of rice bracelet. Owners note subtle color differences between the hardened steel and case, and suggest the bracelet would be more cohesive with endlinks matching the case texture. One owner dislikes the dial and caseback design, preferring a no-date movement and questioning the utility of a 12-hour bezel on a dive watch, finding it lacks a minute/seconds track. Overall, owners rate the Second Hour Shoal Deep — Second Hour highly for its value and bracelet design.
