What people say

Owners + reviewers, side by side

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

Sugess Seestern Vintage S407 600T

Owners widely praise the Sugess Seestern Vintage S407 600T for its exceptional finishing, bracelet quality, and overall value at its price point. Reviewers and owners alike highlight the watch's fantastic looks and build quality, with one owner noting Seestern did a better job than the original inspiration. Some owners report a slight bezel back play and a clunky clasp, while others have no clasp complaints. Accuracy figures vary, with one owner seeing the watch run 2 seconds slow over 30 hours, and another noting a dial leaning slightly left. The watch measures 40mm wide, 14mm thick, and 48mm lug-to-lug, weighing 86g for the head and 163.4g total with the bracelet, leading some to find it heavy for wrists smaller than 7 inches. One owner questioned if the crown felt wobbly when winding or setting. On balance, owners rate the Sugess Seestern Vintage S407 600T highly for its outstanding build quality and aesthetic appeal relative to its cost.

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.
