What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Tissot Gentleman Open Heart

Owners widely praise the Tissot Gentleman Open Heart for its versatile dressy-sporty aesthetic and elegant sunburst dial finish, with one owner preferring its less shiny blue dial compared to other versions. The watch offers excellent fit and bracelet adjustability, and its modified Powermatic 80 movement achieves COSC-level accuracy of -3 to +5 seconds/day, though the seconds hand movement is slightly less smooth at 6 movements per second. However, one owner reported the watch arrived non-functional, requiring a return due to an inoperable movement. On balance, owners rate the Tissot Gentleman Open Heart highly for its aesthetic appeal and accurate timekeeping, despite a reported instance of a faulty movement.
