New Project by MB&F and URWERK: C3H5N3O9, Nitro

by Time&Style Staff

MB&F and URWERK have broken new horological ground with their exciting project called C3H5N3O9, also known as Nitro.

Nitro was created by Maximilian Büsser
 and Serge Kriknoff in a genius collaboration with experimental clock workers Felix Baumgartner and Martin Frei.

The first product within the Nitro project is ZRO12, a limited edition 12-piece zirconium watch featuring a Wankel engine inspired display. The movement was designed by Baumgartner and Frei, the piece constructed by Cyrano Devanthey, and the design by Büsser along with Eric Giroud.

Model ZRO12 displays the hours, minutes and seconds on individual, layered, triangular rotors, all inspired by the Wankel engine design.


This large face, but light weight piece sits comfortably on all wrist sizes and displays the amazing results of this unique collaborative project between MB&F and URWERK.
