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.

William Wood Triumph Chronograph

The William Wood Triumph Chronograph is a Swiss-made chronograph featuring a 41mm stainless steel case and a Sellita SW510 movement. Reviewers highlight its firefighting-inspired design, including a sandwich dial, unique sub-dials, and upcycled fire hose straps. The watch has a 48-hour power reserve, though the movement is often credited with up to 56 hours. Its 16.5mm height and 49.5mm lug-to-lug measurement mean it wears large on a 7-inch wrist, and the handset is described as flat and blocky. Overall, reviewers appreciate the novel design elements and thematic execution of the William Wood Triumph Chronograph.
