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 Globetrotter GMT

The Boldr Globetrotter GMT is praised for its legibility and finishing, featuring applied Super-LumiNova indices and sword hands on a matte black or sunburst blue dial. Reviewers highlight the ceramic bezel's sharp city markings and tight, smooth ratcheting action. The 44mm 316L stainless steel case exhibits a non-traditional design with radial and vertical brushing.
