Parallax Tourbillon

The name ‘Parallax’ is derived from the precision conferred with the legibility of the central seconds hand. Parallax is defined as the apparent change in position of an object when the observer changes his own position. In order to mitigate the possibility of error due to parallax when viewing the seconds hand from an angle, the hand is exceptionally close to the outer chapter ring, marked with neat seconds indices. Additionally, the one-armed balance wheel bridge always runs parallel to the central seconds hand.

The Grönefeld Parallax Tourbillon was awarded the prestigious Grand Prix d'Horlogerie de Genève for the best watch in the tourbillon categorie.
