San Martin Vintage MM300 Automatic SN0087vsSeiko Seiko 5 Sports SKX series

The San Martin Vintage MM300 Automatic SN0087 is praised for its top-notch case and handset finishing, consistent with the brand's reputation. Despite its 44mm case and 14mm thickness, owners report it wears noticeably smaller and fits comfortably on a 7" wrist. Some owners find the design a "messy mixup" and note the lume is an "ugly yellow," preferring BGW9 over C3. One owner found the pin and collar bracelet difficult to resize, with the half-link prone to damage. Overall, owners rate the San Martin Vintage MM300 Automatic SN0087 highly for its impressive finishing and comfortable wearability despite its dimensions.

The Seiko 5 Sports SKX series is widely praised as an excellent value gateway watch, with owners and reviewers highlighting its solid build and powerful lume. The 22mm bracelet is noted for its comfort, and the watch offers numerous style options. Some owners find the original SKX models heavy and bulky, while others appreciate their ruggedness and iconic dive watch design. The Seiko 5 Sports SKX series offers an upgraded movement with hacking and hand-winding, and standard spring bars for easier strap changes. However, it lacks the screw-down crown and ISO certification of the original SKX, leading some to consider it less of a tool watch. On balance, owners and reviewers rate the Seiko 5 Sports SKX series highly for its value and modern features, despite some preferring the tool watch capabilities of its predecessor.
