The Montblanc 1858 Unveiled Timekeeper Minerva Limited Edition introduces a brand-new chronograph function. Instead of using traditional pushers, the chronograph is activated via the fluted bezel. Just one click of the 18K Lime Gold fluted bezel will start the chronograph. A second click will stop it, and a third click will reset it, transforming the chronograph as we know it. The timepiece comes in a 42.5mm 18K Lime Gold case and is fitted with a dark green dial and a green interchangeable alligator leather strap. It is powered by the hand-finished manually wound Calibre MB M13.21 and is limited to 28 pieces.
