The Tecnica Ombre Blanche is one of the most complex timepieces in haute horlogerie because its mechanism houses a minute repeater, tourbillon and perpetual calendar – three complications integrated into a single complete movement.
The rose gold case has been designed to ensure that the minute repeater chime has the best possible resonance in an optimal space. The chimes on the Tecnica Ombre Blanche are called "cathedral" chimes as they form two sets of gongs around the case. The dial features Grand Feu enamelling, created by using the champlevé technique. The process in this case consists of engraving a gold base by creating a hollow which corresponds to the dial area. As the case is very slender for a timepiece which includes a minute repeater, the Tecnica Ombre Blanche is characterised by the quest for refinement obvious in many creations by Parmigiani Fleurier.
