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.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
