Swiss luxury watch maker Thomas Prescher presents Triple Axis Tourbillon Regulator: The world’s only triple-axis flying tourbillon wristwatch.
A triple-axis tourbillon is extremely rare; a triple-axis tourbillon wristwatch even more so. However, Thomas Prescher’s triple-axis flying tourbillon is not simply extremely rare – it is absolutely unique.
Prescher’s Triple Axis Tourbillon Regulator features one of the world’s most exclusive and most difficult complications to assemble, set to stunning advantage in a jet-black natural onyx dial that contrasts beautifully with the pink-gold case. Regulator-style hours and seconds are each indicated in their own separate sub-dial, while the constantly animated tourbillon tracks the minutes during its one-hour rotation.
Thomas Prescher has both an affinity and a talent for complicated tourbillons: while his classmates were submitting simple movements for their watch at the end of apprenticeship school, Prescher presented a half-flying tourbillon that confirmed his position as the top of the form. In 2003 he presented the world’s first pocket watch with a flying double-axis tourbillon. On seeing Prescher’s pocket watch, one of his colleagues mentioned that he thought a double-axis tourbillon was impossible in the constrained space of a wristwatch. Prescher not only met but surpassed the challenge a year later with a wristwatch trilogy of single-axis, double-axis and triple-axis tourbillons.
At this extreme level of micro-mechanical sophistication and miniaturisation, watchmaking ceases to be about timekeeping and becomes pure art. Or perhaps that should read “arts”, because we have both the sublime static beauty of a fine painting in the harmonious forms and colours, as well as the graceful movements of the ballerina in the whorled path traced by the mesmerizing triple-axis tourbillon dancing apparently weightlessly in space.
