Reviews

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

Islander Melville GMT with Grey Hammer Dial

Owners widely praise the Islander Melville GMT with Grey Hammer Dial #ISL-212 for its captivating grey hammer dial, with multiple users calling it awesome and noting that images do not capture its full appeal. The visible blue Islander rotor through the exhibition case back and the orange GMT hand are also appreciated features. Some owners find the 40mm case slightly thick, and a few note that the hands and markers can blend with the dial over time, impacting legibility. Overall, owners rate the Islander Melville GMT with Grey Hammer Dial #ISL-212 highly for its unique dial aesthetic and visible rotor at its price point.

San Martin BB GMT

Owners are broadly enthusiastic about the San Martin BB GMT. One calls the design a handsome mashup of the Black Bay Pro and Explorer 2 that looks rugged yet can be dressed up, and another, after a couple of weeks of wear, says it wears much like a Tudor BB58. Praise for finishing is specific: one owner was struck by the polishing and craftsmanship straight out of the box, while another calls it a steal at €260 for a 20 ATM watch with sapphire crystal, anti-reflective coating, a Seiko GMT movement, and an on-the-fly adjustable clasp. Some owners dislike the clasp as big and clunky, and one reports that screw-down crown threads wouldn't seat and that the brand refused a return until AliExpress refunded him. A few note that later pieces are pricier and often need regulation. Overall, owners rate the San Martin BB GMT highly for its value and finishing, with build consistency and the clasp as the main reservations.
