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.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
