What people say

Owners + reviewers, side by side

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

Marloe Watch Company Motorsport 105

Owners widely praise the Marloe Watch Company Motorsport 105 for its creative dial design, good contrast, and British Racing Green color, with some finding it wears smaller than its 41mm size. One owner appreciates its lack of a date window and comfortable wear on a 6.5” wrist. However, some users note Marloe's 20mm lug width can make models appear top-heavy, and a significant price increase has been observed across the brand's offerings. Overall, owners rate the Marloe Watch Company Motorsport 105 highly for its distinctive dial design and comfortable wearability.

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.
