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.

Geckota Pioneer Automatic

Owners widely praise the Geckota Pioneer Automatic for its retro-futuristic design, impressive lume, and unique dial finishing. The red dial variants are particularly favored for their brushed fumee appearance and vintage feel. Accuracy is noted as surprisingly good for an NH35 movement, though one owner reports +/- 20 seconds per day. The watch is considered a bargain by some at $259, while others find the $519 price for the NH35 movement in a 14mm thick case excessive. The 42mm cushion case is noted to wear large due to its lack of a prominent bezel. A minor phantom date position on the crown is reported, and the crystal is very reflective despite an anti-reflective coating. Some find the gold accents look a bit cheap, and one instance of a loose fleck of lume was observed. Overall, owners rate the Geckota Pioneer Automatic highly for its distinctive vintage aesthetic and value, particularly on sale.
