Developed by Jean-François Mojon with no less than two patents, the avant-garde design and innovative mechanical system of the Klepcys Mars makes this timepiece stand out.

The first innovation comes with the linear display of time, made possible by the timepiece’s one-of-a-kind movement. This movement governs the speed of the wheels pushing the retrograde hours, minutes, and seconds as well as the unusually shaped hour hand. Every 12 hours, the hour hand glides a full 180°, distinguishing daytime from nighttime in the process. As time passes, the hour hand always remains perfectly aligned with the two concentric disks displaying minutes and seconds.

The second innovative aspect of this timepiece is the retrograde date display, placed between 12 and 3 o’clock on the dial. The date is indicated by a rotating jumping cube of 10s that slides changes according to the current date. Lastly, the Klepcys Mars has a 3D-designed miniature of Mars, rotating a full Martian day every 24 hours, 37 minutes, and 22 seconds.
