The C. Purnell Spherion is a high-speed triple-axis tourbillon designed and developed by C. Purnell in collaboration with master watchmaker Eric Coudray and TEC Ebauches. The Spherion, fully customizable, is available in either gold or titanium.

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.



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.
