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 sharp 40mm steel case with unique bezel construction and a glossy dial featuring finely brushed and polished applied hour markers. It is powered by the in-house caliber 0950 automatic movement, which operates at 4Hz and offers a 50-hour power reserve with enhanced magnetic resistance. The limited edition features a black Duratect DLC coated case, a carbon fiber dial, and is regulated to -5/+10 seconds per day. On balance, reviewers highlight the Series 8 870's distinctive case finishing and the robust in-house movement as key strengths.

Horage Supersede Dual Time

The Horage Supersede Dual Time is widely praised for its technically impressive, 98% in-house micro-rotor GMT movement, thin 10mm case, and 39.5mm size, along with excellent finishing and a comfortable bracelet. Owners also note its robust 200m water resistance and 904L steel construction. Some reviewers find the GMT sub-dial illegible, and one owner reported a bezel alignment issue requiring repair, while another flagged the date setting as potentially confusing. The $8,000 price point is considered high by some, though others view it as exceptional value for the movement and build quality. On balance, owners and reviewers rate the Horage Supersede Dual Time highly for its innovative micro-rotor GMT movement and high level of finishing at its price point.
