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.

Lum-Tec Solar Marine

Lum-Tec Solar Marine owners praise its all-black diver design, excellent lume, and rugged, tank-like build. One owner finds it a perfect fit for a 7-inch wrist and the most frequently worn watch despite its smaller size. However, one owner cautions that the PVD coating will wear and chip within a year, impacting its appearance, and another finds the price high for a solar quartz watch with added lume. On balance, owners rate the Lum-Tec Solar Marine highly for its robust design and excellent lume, despite concerns about PVD durability and value proposition.
