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.

Boldr The Boys

Boldr The Boys is praised for its lightweight, durable titanium case, ergonomic lugs, and excellent legibility with strong lume. Owners note the competitive price and good customer service, while reviewers highlight the reliable SII NH35A movement and 200m water resistance. Some owners report that titanium scratches easily and question the brand's history and recognition. On balance, owners and reviewers rate Boldr The Boys highly for its practical features and value at $299.
