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 Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
