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 GT

The Zelos GT is lauded for its value and bold design, with owners highlighting the cool power reserve meter and superb 3-point micro-adjust bracelet. Some owners find the case and lugs could hug the wrist better, and the bracelet is noted as being quite long, requiring significant link removal for a 7.1-inch wrist. The dark green dial, while inspired by Lamborghini, is described as appearing mostly black. Overall, owners rate the Zelos GT highly for its value and the quality of its bracelet at the price point.
