What people say

Owners + reviewers, side by side

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

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.

Yema Superman Gilt CMM.10

Owners and reviewers widely praise the Yema Superman Gilt CMM.10 for its comfortable, slim wearability and captivating gilt-accented sunburst dial, making it a frequent choice for daily wear. The in-house CMM.10 automatic movement is noted for its impressive accuracy, regulated to +5/-3 seconds per day, and a 70-hour power reserve. One owner wished for an option without gold accents, and the bracelet's articulation is mentioned as potentially not suiting smaller wrists, though a 39mm case option exists. Overall, owners and reviewers rate the Yema Superman Gilt CMM.10 highly for its value and comfortable, attractive design.
