What people say

Owners + reviewers, side by side

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

Citizen Series 8 870

The Citizen Series 8 870 is praised for its compelling value proposition and modern Japanese design with a sporty edge. Reviewers note its 40mm steel case, glossy dial with applied markers, and the in-house Calibre 0950 automatic movement offering 50 hours of power reserve and enhanced magnetic resistance. The flat sapphire crystal is noted to collect fingerprints, and the solid caseback omits a view of the movement. The limited edition variant features a 40.8mm black DLC-coated case, a carbon fiber dial, and the 0950 movement regulated to -5/+10 seconds per day. Overall, the Citizen Series 8 870 is viewed as a strong offering for its blend of design and features.

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.
