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.

Zelos Aurora Moonphase

Owners widely praise Zelos for offering excellent value, solid build quality, and enthusiast-friendly designs, with unique dial variants often selling out quickly. The Zelos Aurora Moonphase is noted as a desirable model, though finding one can be challenging. Some owners find Zelos's designs, including those of the Aurora line, to be too flashy for everyday wear, preferring a more subdued aesthetic. One owner reported their Zelos Aurora Nebula 38mm running at -5.3 seconds per day. Overall, owners rate the Zelos Aurora Moonphase highly for its desirable microbrand status and unique dial appeal.
