What people say

Owners + reviewers, side by side

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

Seiko Prospex Marinemaster Marinemaster 1965 Heritage Diver's Watch

The Seiko Prospex Marinemaster 1965 Heritage Diver's Watch is praised for its faithful re-creation of the 62MAS design, with reviewers noting improved wearability due to smaller case sizes (38mm to 40mm) and updated bracelets. Specific models feature a stainless steel case with super-hard coating, ceramic bezel, and a tool-free extension system on the bracelet. Accuracy figures vary, with one model rated at -5/+10 seconds per day and another at -10/+15 seconds per day, powered by movements like the Caliber 8L45 or 6L37 offering 72-hour or 46-hour power reserves respectively. Some reviewers point out drawbacks such as an unsigned winding crown, a lack of tool-free micro-adjust on the clasp for certain models, and a secondary GMT function on one variant. The price point, ranging from $2,800 to $3,600, is considered high by some, especially when compared to other Seiko or Grand Seiko offerings.

Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition

The Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition is praised for its attractive emerald green sunburst dial with gold accents and its comfortable wearability. Owners note the dial looks gorgeous in the right light, and some find it fits better than other models. The watch features a 40mm steel case, a domed sapphire crystal, and 300m water resistance, powered by the 6R55 movement with a 72-hour power reserve. However, some find the watch wears top-heavy due to its density and case design, and the bracelet clasp is criticized for stamped parts and limited micro-adjustment. The retail price of €1,700 is considered high by some, with sales recommended. Overall, owners and reviewers appreciate the dial's beauty and the watch's comfortable fit, despite some reservations about its weight distribution and bracelet clasp.
