Experiment ZR012

C3H5N3O9 is a platform created by Felix Baumgartner, Maximilian Büsser, Martin Frei and Serge Kriknoff to experiment with concepts, ideas and creations without the inherent limitations of a luxury brand.

Indications: Experiment ZRO12 indicates hours and minutes with two Wankel engine inspired eccentric rotating Releaux polygons (triangular-shaped rotors). Hours are indicated by the lower rotor along the front of the 'dial', while minutes are indicated by the smaller upper rotor.
Epitrochoid curves: Time is by the tips of the Releaux polygon rotors tracing epitrochoid curves. To create the complex shape of the hour and minute epitchroid curves with the high precision required, 180 separate points were plotted. There is tolerance of just o.2omm between the triangular rotors - the special shape is actually called a Releaux polygon - and the hour and minute marked epitrochroids surrounding them.
Complication: The Releaux polygon (triangular-shaped) rotors are eccentric, i.e. not mounted directly to the central 'crankshaft' and they demand considerable time, skill and patience to set up correctly in assembly process. To ensure extremely high precision adjustment, the fixed wheels can be rotated slightly (then re-fixed) to allow fine adjustment and synchronised precision between the hour and minute indicators.
Case: The case and lugs of Experiment ZR012 are made from zirconium, which is derived from the mineral zircon. Visually zirconium is similar to titanium and is highly resistant to corrosion. The case dimensions are 55mm x 44mm (excluding lugs). The articulated front lug and compound rear lug wrap ergonomically around the wrist and ensure a high level of comfort.
Power reserve indicator: Turning Experiment ZR012 over reveals the power reserve indicator. The movement has autonomy of 39 hours and is wound by a large screw down crown.
