Unveiled in 2015 by 4N watch brand founder François Quentin, the 4N SAPPHIRE PLANET is an evolution in the design of the 4N MTV-01 wristwatch watch across a new case in Sapphire.

The concept was to promote, across transparency, the mechanical movement with manual winding developed with APRP who issues 237 h of power reserve and to be able to admire a big number of 514 components decorated at the hand, which it is made. Its exclusive mechanism of the hours and minutes jump can so be admired, every minute, according to different angles, and show the tremendous complexity of the kinematics of discs such planets in motion. Created as an avant-garde answer to the evolution of the design of the numerical watches, 4N proves with the SAPPHIRE PLANET that it is possible to link clarity, elegance and technical nature, with a perpetual visual show.
François Quentin worked in close cooperation with FashionLab 3D of Dassault Systèmes to work out this new model, across tools 3D CATIA. Objective was to compromise with at the same time this new material and these visual effects, but also to anticipate optic aberration by the form of the case.

The technical challenge was also huge, the case sapphire is manufactured in one piece included the glass. Hundreds of the hours are necessary for the machining of one case.

The 4N SAPPHIRE PLANET is an edition limited to 3 pieces, completely customizable by colour and the markings on the intermediate glass.
