What people say

Owners + reviewers, side by side

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

Oris ProPilot X Calibre 400 Laser

The Oris ProPilot X Calibre 400 Laser is praised for its high-tech laser-etched titanium dial and the advanced Calibre 400 movement with a 120-hour power reserve. However, the dial's unique rainbow gradient is polarizing, with one owner finding it childish and preferring applied indices for better legibility and lume, while reviewers note the case shape may still require adjustment. The CHF 4,800 price is also flagged as steep for a time-only watch. On balance, owners and reviewers acknowledge the innovative dial and movement, but opinions are divided on its aesthetic appeal and value proposition.

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.
