San Martin Vintage MM300 Automatic SN0087vsSeiko Prospex Sea 1968 Heritage Diver's GMT Limited Edition

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 Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition is widely praised for its excellent quality and finishing for its price, with reviewers highlighting its beautiful case, bracelet, and Lumibrite lume. Owners appreciate the comfortable 42mm case size and the 4 o'clock crown position. The watch features a sapphire crystal and uses the in-house 6R54 automatic movement with a three-day power reserve. Some reviewers note that the GMT function is secondary and that the bezel clicks are quieter than expected. The 4:30 date window splits opinion among enthusiasts, and it is described as a "caller GMT" rather than a true "traveller GMT." Overall, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition highly for its excellent value, quality finishing, and comfortable wearability.
