Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Out of Order 40mm GMT Automatic for its playful and unique distressed aesthetic, with many appreciating its distinct personality and non-Rolex clone colorways. The Seiko NH34 movement is noted as a positive upgrade by some. However, the intentionally damaged look is polarizing, with some finding it gimmicky. The stock leather strap is considered cheap by one owner, and the case finishing on one variant did not fully match its "Ultra Brushed" name. Accuracy figures vary, with one owner reporting gaining only a few seconds in six hours, while another noted a range from +1/+2 to about -6 seconds per day. Overall, owners and reviewers rate the Out of Order 40mm GMT Automatic highly for its unique personality and aesthetic at its price point.
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.
