Reviews

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 impressive finishing and textured dials, with the blue dial and bracelet play of light specifically noted as luxurious and comfortable on the wrist. The watch utilizes the Miyota 9051 automatic movement, offers 100m water resistance, and features a 40mm case. Accuracy is reported between -10 to +20 seconds per day with a 42-hour power reserve. On balance, owners and reviewers rate the Citizen Series 8 831 highly for its luxurious feel and dial finishing 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

Owners widely praise the Zelos GT for its value and materials that exceed expectations, with particular appreciation for the power reserve meter and the superb 3-point micro-adjust bracelet. However, some owners find certain designs too aggressive or oversized, and one owner noted the dark green dial mostly appears black. The bracelet is described as extremely long, requiring significant link removal even for a 7.1-inch wrist. Overall, owners rate the Zelos GT highly for its value and bracelet adjustability at its price point.

From video reviewers

The dial's subtle light play and the inclusion of a Miyota 9133 movement with a power reserve indicator are noted strengths. Reviewers did not reach a consensus on any weaknesses.
