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.

Zelos Mako 4

Owners widely praise Zelos' dial finishing, with specific admiration for blued markers and hands, and the unique titanium bezel insert. Reviewers highlight the Mako 4's impressive case finishing and fully lumed ceramic bezel for its price point, noting the boxed sapphire crystal and wavy dial texture contribute to a vintage feel. The Sellita SW200 movement is described as reliable, with one owner reporting accuracy of -0.3 seconds per day. However, the crown can be difficult to grip, and the winding mechanism offers resistance when screwing down, while the watch's height may hinder wearability under a suit cuff. The tropic rubber strap is considered excellent, in contrast to a stiff leather option. On balance, owners and reviewers rate the Zelos Mako 4 highly for its exceptional dial and case finishing at its price point.
