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 Jazzmaster Performer Automatic

Owners widely praise the Hamilton Jazzmaster Performer Automatic for its clean design, comfortable wearability, and impressive 80-hour power reserve, with accuracy averaging just over 2 seconds per day. Some owners note the bezel is non-functional, and one experienced an internal movement failure causing time jumps, though service resolved this. The 34mm variant is considered solid for smaller wrists due to its flatter crystal and reasonable lug-to-lug distance. On balance, owners and reviewers rate the Hamilton Jazzmaster Performer Automatic highly for its blend of style, comfort, and extended power reserve at its price point.
