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.

Hamilton Khaki Aviation Day Date Auto

Owners and reviewers widely praise the Hamilton Khaki Aviation Day Date Auto for its handsome, legible dial with raised indices and day/date complications, and its versatile, modern pilot watch design. The fully brushed case and good lume are noted strengths, with one owner finding it wears comfortably on a NATO strap. The H-10 caliber offers an 80-hour power reserve, though its decoration and regulation are less refined. Some find the 42mm size large and the skeletonized hour hand tip visually unappealing, while others note the AR coating is decent but not exceptional. Overall, owners and reviewers rate the Hamilton Khaki Aviation Day Date Auto highly for its practical design and value at its price point.
