Montblanc Heritage Chronométrie ExoTourbillon Minute Chronograph Vasco da Gama

Launched as a SIHH 2015 novelty, this version of the Montblanc ExoTourbillon Chronograph is the flagship of the Vasco da Gama Limited Editions from Heritage Chronométrie Collection. Each of the 60 chronographs in this strictly limited edition boasts several important artisanal refinements.
Montblanc’s ticking flagship is naturally affiliated with Vasco da Gama’s floating flagship, the São Gabriel. The pane of sapphire crystal in the case back is adorned with a sketch of the historic sailing vessel, as is the signature of the intrepid discoverer and seafarer.
The series is limited to 60 watches in reference to the 60-man crew of the São Gabriel. The sophisticated dial with different levels and refined finishes reflects the two complications of the timepiece.
The upper part embellished with a slice of aventurine, dyed dark blue, catches the eye on the dial, where numerous small dots emulate the starry night sky in reference to the night sky of the southern hemisphere that guided Vasco da Gama on his voyage. A diamond in the patented cut in the shape of the Montblanc emblem sparkles at 12 o’clock.
A wave shaped guilloché, designed in flinqué style and coated with blue paint, in the centrally positioned hand-type date display refers to the nocturlabium (star clock), which was one of the navigational instruments aboard the São Gabriel.
The dial’s lower level is satin-finished and unveils the intricate construction of the ExoTourbillon at 6 o’clock. This exceptional timepiece is available in a 44-mm white gold case.
