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 GT

The Zelos GT is lauded for its value and bold design, with owners highlighting the cool power reserve meter and superb 3-point micro-adjust bracelet. Some owners find the case and lugs could hug the wrist better, and the bracelet is noted as being quite long, requiring significant link removal for a 7.1-inch wrist. The dark green dial, while inspired by Lamborghini, is described as appearing mostly black. Overall, owners rate the Zelos GT highly for its value and the quality of its bracelet at the price point.
