CHPTR_Δ.3 MDP – A triangular reading of time, signed BA111OD
CHPTR_Δ.3 (Chapter Delta) is the first watch complication developed by BA111OD , in collaboration with master watchmaker Olivier Mory . This unique timepiece reinvents the way we read the time thanks to a novel hypocycloidal reading , where time doesn't turn—it dances.
🌀 A reading of time in a triangle
Satellite time wheel rotating around a fixed central wheel
Cycloidal deltoid trajectory: the hour hand describes a moving triangle
Visual duality between the circular time of the minutes and the geometric time of the hours
A mechanical choreography that slows down, starts again, and symbolizes the carousel of life.
