Montblanc Unveil New Look For Secret Minerva Monopusher Chronograph

Montblanc Unveil New Look For Secret Minerva Monopusher Chronograph

Montblanc has unveiled a new limited edition in distressed steel, of the Secret Minerva Monopusher Chronograph – first launched in 2022 – giving this model a more contemporary look. 

This distressed steel finish is achieved by treating the 43mm stainless steel case with a black coating. The material is then manually washed and brushed with quartzite from the Mont-Blanc and limestones from the V-shaped mountain opposite the Villeret Manufacture, called La Combe Grède, bringing the mountain and the valley together. This interesting treatment gives each timepiece its very own individual patina and appearance.

This new version comes with a white gold fluted bezel inspired by Minerva’s first fluted bezel that dates back to 1927, adding a new level of finesse to the model. It is fitted with a black nubuck alligator strap with a distressed steel triple-folding clasp, and includes a caseback featuring an engraving of the historic Minerva Manufacture.

The Montblanc Unveiled Secret Minerva Monopusher Chronograph Limited Edition features a historic hand-wound Minerva MB M16.29 movement with all its meticulous hand-finishing. This mesmerizing movement has been flipped over to display all the mechanical action on the dial side of the watch. At first glance, the viewer may think it is a skeletonized movement, but a closer look reveals that this historic chronograph movement is on full display on the dial side of the watch.  

This is one of the first times in Minerva’s 165-year history that a timepiece features the movement on the dial, making it an object of desire for watch lovers who wish to admire the movement without altering their timepiece. Looking through the sapphire crystal into the depths of the movement, the viewer can immediately perceive the detailed level of finishing on the sanded German silver movement and the beauty of the bridges and plates that have been coated with anthracite ruthenium to match the tone of the case.
