Franck Muller presents the calibre 1700


Franck Muller is proud to present its movement entirely made in-house. By Creating this movement, Franck Muller wanted to carry on the handsome movements of La Vallée de Joux of the 30s. The caliber 1700 is the quintessential rendering of the traditional art of watchmaking. The whole movement is composed of 213 components. The uniqueness of this calibre is that it features a 7 day power reserve, which is 168 hours. To achieve this level of performance, the movement has been fitted with 2 barrels.




The movement is fitted of a high performance escapement, with a pierced and lighter wheel.

In addition, the escapement features a high-end screwed balance wheel, which also requires extreme precision to adjust.

The wheels are chamfered and circular grained. These decorations, characteristics of Haute Horlogerie, are realised not only for aesthetics, but also to unify and soften the surface.

Following the standards of watchmaking centuries ago, Franck Muller has decided to continue this tradition of making bearings that preserve and protect the jewels. Perlage is made on the main plate of the movement, looking both beautiful inside the case and outside. With refinement, all the bridges are delicately decorated with Côtes de Genève stripes. In addition, each bridge is hand bevelled to perfection, creating absolute harmony between the crisp corners and interlacing the curves.

The finishing of this movement, the care, patience and attention to detail given to every component is tremendous. This calibre is truly an exquisite work of art in total respect to watchmaking traditions. 




The bridges are decorated with Côtes de Genève stripes. Adorned with rubies which are set in bezels, 18k gold.

The raquette is used to modify the operation of the watch by shortening or lenghtening the hairspring.
