Spherion


The inner tourbillon cage of Spherion’s triple-axis tourbillon makes more than seven rotations each minute (less than eight seconds); the inner, middle and outer tourbillon cages all rotate at higher velocities than previously attained in a triple-axis tourbillon: 8 seconds, 16 seconds, and 30 seconds respectively.

This sensational technical achievement is worthy of an equally spectacular case to highlight the triple-axis tourbillon. C. Purnell developed a highly complicated and unusual sapphire crystal, which added more than a year to the development of the Spherion; creation of this sapphire crystal required fourteen months of research and development to acquire the optimal shape and quality.

Crystal Window

The result is an astonishing sapphire crystal window with a vertical wall at 6 o’clock stretching all the way to the bottom of the case to provide an unimpeded view of the multi-axis tourbillon. The complex case and crystal design are both critical features for optimally displaying the tourbillon in action.

Variations

Spherion is presently available in a choice of polished, satin-blasted or black DLC-coated grade 5 titanium, 18kt rose gold, or 18kt white gold, and comes with a three-year warranty extendable to five years by registering with C. Purnell.
