Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
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.
Owners widely praise the Longines Hydroconquest for its attractive sunburst blue dial and accurate timekeeping, with one owner reporting a loss of only 2 seconds per day. However, the bracelet is frequently criticized for lacking micro-adjustments and having pinch-prone links, and the screw-down crown is noted as inconvenient and difficult to operate by multiple owners. Some owners also flag the bezel action as ratchety with back play, and one owner found the lugs sharp and the overall design uncomfortable, leading them to sell the watch. On balance, owners appreciate the Longines Hydroconquest's aesthetic appeal and value, despite significant reservations about its bracelet and crown usability.
The bezel action is praised for its smooth and precise rotation. Lume brightness is a shared weakness, found to be somewhat lacking. Reviewers disagreed on the watch's value proposition compared to alternatives.
