The DC 80 project is based on a patented chronograph development named C51, based on the proven Valjoux 7750. Our benchmark for the modification of the caliber 7750 was to significantly increase the readability of the chronograph function. For that reason we put our main focus on the technical realization of a jumping 60-minute stop hand out of the center.


This new patented construction allows to record stoping times even more easily, faster and more accurately. The Lemania 5100 movement so far set a pattern for a clear and unambiguous readability.

Our new construction has two advantages in terms of readability:

First: 60 minutes are now shown in just one complete turn of the center hand rather than the usual 30 minutes, while the assigned minute scale is counted over the full dial.

Further advantages of this movement modification are the possibilities of adding an independently adjustable second time zone, which can be operated by the crown at 3 o’clock. In addition to that the new movement allows a larger date display directly under the dial. The date wheel is closer to the dial though, as opposed to some module calibers.


The DC80 model signifies a new chronograph line with the most diverse increments of our new caliber C51. All parts required for the new C 51 caliber, such as plates, wheels, pinions, etc. are produced in our manufactory.

With pleasure you can preorder this model. It will be available in autumn 2017.
