Nezumi Studios BaleinevsYema Diver

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.

One owner reported a water ingress issue on their Yema Diver the first time it got wet in a lake, despite rinsing and inspecting the watch and bezel. Another owner notes this manual wind Yema Diver has a cool patina but is unlikely to be waterproof or gain value. Overall, owners view the Yema Diver as a fun second watch rather than an investment.
