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.

Fortis Stratoliner S-41

Owners widely praise the Fortis Stratoliner S-41 for its purpose-built design and outstanding details, particularly its space blue lume and bright orange date on the dial. Reviewers note the WERK 17 movement offers a 60-hour power reserve. However, the Fortis Stratoliner S-41's 41mm case thickness and lug-to-lug distance lead some to perceive it as wearing large, and the dial's small text and flat design are flagged as potential drawbacks. Overall, owners and reviewers highlight the Fortis Stratoliner S-41's unique design and innovative movement as its primary strengths.
