Seed VMF 5440 extra-thin flying tourbillon micro-rotor 13.5”’


Drawing on the company’s expertise in crafting extra-thin movements, the Seed VMF 5440 is just 3.4 mm

thick. Its robust and sophisticated construction incorporates all the advantages of the tried-and-tested

VMF extra-thin calibers. It is wound by a micro-rotor, cleverly integrated into the movement so as to

maintain its slim profile.

Deviating from previous designs, the tourbillon is purposefully located at about 7 o’clock, clearly distinguishing

it from existing VMF Tourbillon movements –the tourbillon of the automatic Seed VMF 3024

and extra-thin hand-wound Seed VMF 5430 are positioned at 6 and 9 o’clock respectively.
