The Grönefeld Parallax tourbillon features a “flying” tourbillon with a large central seconds hand, stop seconds, power reserve indicator and winding-setting function indicator. The in-house movement, beautiful solid silver dial and highly polished case display sophistication and craftsmanship at the very highest level. The raised flying tourbillon allows full appreciation of the concentric, rhythmic “breathing” of the balance hairspring, while ensuring high precision. The name “Parallax” is derived from the precision of the readability of the central seconds hand. Parallax is defined as the apparent change in position of an object when the observer changes his own position.
The Grönefeld Parallax Tourbillon was awarded the prestigious Grand Prix d’Horlogerie de Genève for the best watch in the tourbillon category.
A highly-polished stainless steel sleeve around the tourbillon draws further attention to the beautiful escapement by reflecting the oscillating balance wheel and the rotations of the escape wheel and tourbillon cage. Normally a central seconds hand requires a friction spring to prevent small fluttering caused by play in the gear train. But for the Parallax Tourbillon, the Grönefeld brothers developed the movement with an added pinion and wheel so that the energy-sapping friction spring is not required. The latter feature improves power transfer to the regulator, contributing to the impressive power-72-hour power reserve.
