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.

Dryden Chrono Diver Series 1

The Dryden Chrono Diver Series 1 is a 42mm mechaquartz chronograph featuring a dual-curved sapphire crystal and 100m water resistance. Owners note the VK63 movement's characteristic chronograph hand not resetting perfectly to zero, a trait present on this specific watch. The case exhibits polished chamfers on the upper lugs, and it utilizes Swiss Superluminova BGW9. On balance, owners appreciate the classic case shape and dial design of the Dryden Chrono Diver Series 1 at its price point, despite the mechaquartz movement's known reset behavior.
