What people say

Owners + reviewers, side by side

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

Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322

Owners widely praise the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 for its gorgeous, color-popping black mother-of-pearl dial and good case finishing, with some appreciating its distinct bead-blasted case and H-link bracelet. The $375 price is noted as a strong value for a true mother-of-pearl watch. However, opinions are divided on the dial text font and the Islander logo, with some finding them unattractive and others seeing them as minor issues on an otherwise appealing tool watch. On balance, owners rate the Islander Thunderbolt Pilot Watch with Black Mother of Pearl Dial #ISL-322 highly for its striking mother-of-pearl dial and value proposition.

Lum-Tec Solar Marine

Lum-Tec Solar Marine owners praise its all-black diver design, excellent lume, and rugged, tank-like build. One owner finds it a perfect fit for a 7-inch wrist and the most frequently worn watch despite its smaller size. However, one owner cautions that the PVD coating will wear and chip within a year, impacting its appearance, and another finds the price high for a solar quartz watch with added lume. On balance, owners rate the Lum-Tec Solar Marine highly for its robust design and excellent lume, despite concerns about PVD durability and value proposition.
