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.

Grand Seiko SLGH017

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.
