What people say

Owners + reviewers, side by side

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

Sugess Seestern 62MAS V3

Owners widely praise the Sugess Seestern 62MAS V3 for its comfortable 38mm size, excellent finishing, and impressive lume, with many noting its great value for money. The watch features a full lume ceramic bezel insert and a high-quality bracelet with solid links and a milled clasp. Some owners report minor issues such as bezel misalignment or backplay, a slightly wide bezel, and a fully reflective bezel insert that can clash with the crystal, while others mention unevenness on the backside of the crystal causing secondary reflections or a "milky ring." On balance, owners rate the Sugess Seestern 62MAS V3 highly for its compact size, excellent finishing, and value.

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.
