The Thomas Prescher Triple Axis Tourbillon Regulator is the world’s only triple-axis flying tourbillon wristwatch. This horological art piece is not only extremely rare, it is also unique. It houses one of the world’s most exclusive and most difficult complications to assemble.
Equipped with a hand-wound mechanical calibre, Thomas Prescher’s Triple Axis Tourbillon Regulator watch features three sub-dials. The largest among them indicates the seconds along with the mesmerizing choreography of the triple axis flying tourbillon mechanism. The other two sub-dials respectively indicates the hour and minutes.
The Triple Axis Tourbillon Regulator watch model featured here comes with an 18K pink gold case measuring 43mm in diameter and a natural black onyx dial. It is also available in platinum.
