At just 9.1mm thin, this most recent member of the Vanguard line is available in either 37mm or 41mm versions – both equipped with a new bespoke movement created by Franck Muller. This new timekeeping engine is an ultra-thin automatic winding movement designated Caliber MVT FM 708-SQ. Designed, engineered, built, and regulated completely in-house; 136 components comprise the slender 3.83mm profile of the new skeletonized caliber. 

Each component is decorated by hand and reaffirms Franck Muller’s savoir-faire, while simultaneously offering a stunning view of the architecture of hand finished components housed within the svelte profile of the Vanguard’s coachworks.  Offered in Steel, titanium, 18kt gold and solid platinum, Vanguard’s slim skeleton can also be ordered bedecked with white or black diamonds on the outer case as well as the numerals to add even more luster to this already shining gem of a timepiece. Stylish and comfortable to wear thanks to the curved case and back, the Vanguard Slim Skeleton is now available to order through your local Franck Muller authorized dealers.

Prices range from $35,900 for both the titanium and steel versions, up to $87,000 for the diamond bedecked platinum edition.  For more information or to order yours, please contact
