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.

Sternglas Naos

The Sternglas Naos is widely praised for its refined daily wearability and Bauhaus design, with owners noting its durable construction, scratchless sapphire crystal, and flawless date mechanism. Reviewers highlight the comfortable and supple bracelet that drapes well and a date window that matches the dial. One owner advises replacing the original tan strap due to a lack of durability. The quartz movement is noted for its accuracy, and the absence of a seconds hand is seen as a unique solution to prevent misaligned markers. Overall, owners and reviewers rate the Sternglas Naos highly for its harmonious design and comfortable wear at its price point.
