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 8 831

Owners widely praise the Citizen Series 8 831 for its finishing, with one owner noting it exceeded expectations. Reviewers highlight the textured Ice Blue dial and the bracelet's play of light, contributing to a comfortable and luxurious feel on the wrist. The watch features a 40mm ion-plated stainless steel case, a sapphire crystal, and 100 meters of water resistance. It is powered by the in-house Miyota Caliber 9051 automatic movement, which has a 42-hour power reserve and an accuracy range of -10 to +20 seconds per day. On balance, owners and reviewers rate the Citizen Series 8 831 highly for its impressive finishing and dial design at its price point.

From video reviewers

The case finishing, with its contrasting brushed and polished surfaces, is a notable strength. The 40mm case size and comfortable fit are also consistently mentioned. Reviewers did not reach a consensus on any weaknesses.

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.
