Perrelet A1051/4 description
Bigger, more powerful and even more sensational, the Turbine XL is astounding observers with its audacity and proportion. The cases with their dynamic and fluid lines, in PVD steel or titanium, house the technology of the Double Rotor, once again featured as a hallmark. The 12 turbine blades in titanium, which seem to be designed to slice through the air, slip under the black interior flange. The optical impact of this unique and unusual watchmaking specialty is even greater.
The present version has a stainless steel case with PVD coating.
