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 Sea Save the Ocean Special Edition

The Seiko Prospex Sea Save the Ocean Special Edition is widely praised for its attractive, unique, and textured dials, often described as having a "Grand Seiko feel" at a more accessible price point, with specific mentions of wave patterns, lagoon hues, and manta ray motifs. Owners appreciate the smooth bezel operation and satisfactory lume. Accuracy figures vary, with one owner reporting +5 seconds per day, while another notes a range from +1/+2 to about -6 seconds per day. The 6R35 movement offers a 70-hour power reserve, and some models feature sapphire crystals. Criticisms include a desire for exhibition casebacks and concerns about the quality and security of the stamped metal clasps and bracelets, which are frequently described as rattly or underwhelming, though this is noted as a common Seiko trait. Some owners are split on the number of Save the Ocean variations and dislike the cyclops magnifier.
