Franck Muller challenges the boundaries of fine watchmaking even further with the unveiling of the Vanguard™ Slim Skeleton. This collection combines a slim movement, entirely manufactured in-house, with the iconic Vanguard case and numerals. The Vanguard™ Slim Skeleton asserts its personality and remarkably balanced proportions through its graceful slimmer case (9,1 millimetres). The master watchmakers have once again achieved a work of art by curtailing the case thickness to a minimum while conserving its character, accuracy and technical features. Furthermore, the watchmakers have also rethought a unique skeleton movement, manufactured in-house, and dedicated to the Vanguard™ Slim Skeleton collection. The slim movement benefits from an automatic winding and 38 hours of power reserve.
