What people say

Owners + reviewers, side by side

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

Phoibos Wave Master

Owners widely praise the Phoibos Wave Master for its attractive wavy dial, bright lume, and comfortable engineer bracelet, with many considering it one of the best-looking watches under $300. The watch features a sapphire crystal and ceramic bezel, and owners report good quality for the price, with a subtle wave pattern on the dial appreciated for its unique style. While some minor finishing flaws like slightly crooked hour markers or an off-center outer ring have been noted, these are generally considered not visible during wear. One owner experienced a clasp breakage after four years, but Phoibos replaced it free of charge. Some owners wish the watch were larger than 40mm, and one notes the GMT hand and other details may not hold up under extreme close-ups. Overall, owners rate the Phoibos Wave Master highly for its distinctive dial and value, especially considering its build quality and features.

From video reviewers

The unidirectional ceramic bezel action is praised. The lume brightness is noted as a weakness. Reviewers disagree on the water resistance rating, with some stating 300M and others 200M.

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package.

Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.
