The Franck Muller’s Grand Central Tourbillon explores a rare tourbillon variant in the manufacture’s signature style
Tourbillons have long been a symbol of haute horlogerie. In modern wristwatches, however, these devices don’t quite serve their original purpose of counteracting gravity’s effects on the balance’s precision and accuracy. Instead, tourbillons function more as a demonstration of watchmaking savoir faire—as well as a source of much visual interest. As they become more common, different variants have been developed, from multi-axial tourbillons and their complicated dances to movements with multiple tourbillons.

Among these variations on the theme, the central tourbillon remains relatively rare. It is also a far more recent development that was only patented in 1995, despite the tourbillon’s long history dating back to 1801. This variant is uncommon largely due to technical reasons. For a start, putting the tourbillon in the middle of the dial takes up space, which requires the movement’s architecture to be revised. This extends to a rearrangement of the gear train, of course, including the motion work that holds (and turns) the hands to display the time.
The technical hurdles to overcome in a central tourbillon are not trivial. Franck Muller has, however, gone ahead to offer its take on this concept last year with the Grand Central Tourbillon in an updated Cintrée Curvex CX case. The brand has followed up with a smaller model this year to suit an even wider range of wrist sizes for connoisseurs.
