Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the San Martin Diving SN0009's stunning looks, top-notch finishing, and build quality, with one owner noting its resemblance to a Grand Seiko and another highlighting crystal clarity. The watch features an enamel dial and updated BGW-X1 lume, and the smooth caseback and bracelet contribute to comfortable daily wear. Some owners find the 44mm case to be a "thick boy" at 13mm, and a few express that its proportions and dial are less classy than alternatives, with one noting the bracelet is less refined than previous versions. One owner reported receiving a unit with scratched AR coating and encountered significant warranty claim issues. Overall, owners rate the San Martin Diving SN0009 highly for its impressive finishing and build quality at its price point.
Owners praise the Thorn Vintage 50-Fathoms Automatic Men Watch for its retro diver aesthetic and improved detailing, with many finding the case finishing excellent and the overall construction and design superior to certain alternatives. However, some owners note potential improvements in dial and bezel alignment, and one owner found the included NATO strap unsatisfactory. A reviewer flagged the mineral glass as a drawback and stated the lume was not as bright as other brands, though long-lasting. One owner reported the lugs felt too long, while another found the 50mm lug-to-lug wearable on a larger wrist. The Seiko NH35 movement is functional, though some suggest an NH38 would be better suited for the no-date dial. Overall, owners rate the Thorn Vintage 50-Fathoms Automatic Men Watch positively for its compelling vintage styling and good value, despite minor points of contention regarding alignment and strap quality.
