Introducing the Montblanc Tourbillon Cylindrique Geospheres Geosphères Vasco Da Gama.  Yea, it’s a mouthful, but this piece from the Montblanc Villeret collection, it’s most prestigious  is an incredible watch.  Montblanc has just killed it here in form and function.  It is a timepiece that unites for the first time ever a cylindrical tourbillon and unique, functional worldtime indication. This is the very limited Tourbillon Cylindrique Geosphères Vasco da Gama from the Villeret collection. This watch is very impressive. The 47mm red gold encloses a glittering panoply of complication and finishing, that showcases what Villeret can do. The watch is dominated by three large spheres at the top is the giant tourbillon, with three dimensional bridge and cylindrical mainspring which aside from looking great is a nod to the marine chronometry that fits in with the Vasco da Gama narrative of exploration.

Given the high-end spec and matching price, this is not a watch for everyone. That’s what the rest of the Montblanc collection is for. This piece is intended to demonstrate Montblanc’s high end capacity and legitimacy in the high horology space. Given that Montblanc are only producing 18 of these watches, pricing is from 250.000 euros which means it might not arrive in malaysia on retail.
