De Grisogono’s Otturatore timepiece combines four complications into a compact face without clutter. And it does through a selective display system powered by its own mainspring and barrel. At any one time, only one of four small sub-dials is displayed—seconds, date, moonphase and power reserve. Click a button, and the mobile selective display dial travels 90 degrees to reveal the next sub-dial.
It is a simple, satisfying effect that is realized using an auxiliary module comprising 334 parts.
The selective display system is wound manually by depressing a button next to the crown, and then activated by pressing another button. The real technical challenge in designing the movement was a damping system that could arrest the hypervelocity of the mobile dial without breaking apart.
The Otturatore is an interesting piece that, while fitting in well with de Grisogono’s existing collection, especially the Instrumento Uno, also holds the potential for many new references in the future.
When launched in India, the Otturatore will be priced between R3.71 lakh and R3.82 lakh depending on case material.
