Franck Muller 7 Days Power Reserve Skeleton

Unveiled at the 24th edition of the World Presentation of Haute Horlogerie (WPHH), this 7 days Power Reserve model is a Franck Muller classic dressed in a new skeleton avatar.

The uniqueness of this skeletonized collection is the caliber 1740 that features a generous 7 days Power reserve. Powered by 2 barrels, this mechanical movement is precisely designed, manufactured and decorated in-house. The bridges are hand-chamfered, an essential element of decoration in Haute Horlogerie, which is the result of a long and meticulous work.

After months of dedication, Franck Muller has adapted the caliber 1700 into a skeleton form that reveals a highly technical mechanism and perfect styling. The high precision caliber 1740 is adorned by 21 jewels. This model is available in an 18-carat gold or stainless steel version in a Round or Cintrée Curvex casing.
