Inspired by the golden age of trade and travels across the Atlantic Ocean, this sophisticated timepiece in the Montblanc 4810 Collection introduces the new Manufacture Caliber MB 29.21 while manifesting a classically elegant design. Endowing Montblanc’s patented Exo Tourbillon with a highly functional stop-seconds mechanism, the new automatic caliber allows for setting the time precisely to the second. Smaller than standard rotors, the movement’s ultra-velocity micro rotor balances performance and precision while enabling a lighter and slimmer construction. Bearing rose gold-plated Roman numerals and indexes as well as rose gold-plated regate hours and minutes hands, the silvery-white dial exhibits an exploding Montblanc star pattern on the upper part, while the Exo Tourbillon is surrounded by a refined “Côtes de Genève” guilloché pattern. The 42 mm rose gold case features straight horns, which are rounded to better suit the wrist of the wearer. With ultimate functionality and longevity ensured by the Montblanc Laboratory Test 500, the Exo Tourbillon stop-seconds complication bestows this fine lifetime companion with everlasting precision.
