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 Heartlander Solar

The Dryden Heartlander Solar is widely praised for its wearability, with its 38mm case and thin profile making it a versatile, go-anywhere watch. Owners and reviewers highlight its exceptional lume, comfortable president-style bracelet, and compelling $500 price point. The solar power feature is appreciated for its convenience, eliminating the need for winding. Some owners note the 38mm case can feel small on wrists just under seven inches, and one reviewer flags that the prominent crown may irritate some wearers. The use of a Miyota movement is seen as a positive for durability and affordability. On balance, owners and reviewers rate the Dryden Heartlander Solar highly for its excellent wearability and value at the $500 price point.
