Our new skeleton movement has been designed around soft curves, deliberately contrasting with the robustness and strength of the Vanguard case. The easily recognisable bold and iconic numerals of the Vanguard collection have been maintained in order to balance with the contours of the skeleton movement. The Vanguard Slim Skeleton also marks the debut of a brand new case size for Franck Muller, the V 37, making the timepiece even more wearable by both genders. The 9.1 mm thin Vanguard Slim Skeleton benefits from an automatic winding system and a 38-hour power reserve. It boasts remarkably balanced proportions despite trading in the signature oversized appeal of the classic Vanguard for a gracefully slimmer profile in both the V 41 and the new V 37 case sizes, all the while maintaining a palpably three-dimensional feel to its form. Featuring a similarly sporty design seen in its original form, the side insert is a smooth clean line which follows and highlights the sleek contours of the curved case on its profile.
