Montblanc Unveiled Secret Minerva Monopusher Chronograph Limited Editions

The new Montblanc Unveiled Secret Minerva Monopusher Chronograph Limited Editions not only feature this iconic hand-wound MB 16.29 movement with all its meticulous hand-finishing, but the movement has been flipped over to display all the incredible mechanical action on the dial side of the watch.

Looking through the sapphire crystal into the depths of the movement, the viewer can immediately perceive the incredible level of finishing on the sanded German silver movement. This incredible mechanical caliber emphasizes the Maison’s special snailed diamantage coquille motif and polishing, which includes the inner angles of the components.

In keeping with all Montblanc’s highly complicated movements, the iconic Minerva arrow and the Maison’s “V”-shaped bridge are also on display. The Minerva arrow is a tribute to the Roman Goddess who is always depicted with her arrow-tipped staff in hand, and the unusual “V”-shaped bridge comes from the view of the mountains seen from the watchmakers’ window in Villeret, a sight that has been a constant since the founding of the workshop in 1858.

Particular attention has been paid to the indications so that they don’t distract from the movement with an open-worked 30-minute chronograph counter, an open-worked small seconds display, and elegant hands and indexes that have been enhanced with Super-LumiNova® for enhanced legibility.

In addition to the upside-down chronograph movement, the Montblanc Unveiled Secret Minerva Monopusher Chronograph Limited Editions include a fluted bezel inspired from a Minerva design that dates back to 1927. This strong design element frames the movement and further accentuates all the horological expertise that makes these timepieces so special.

There are two limited editions of 18 and 58 pieces, in Lime Gold and stainless steel respectively. Both come in a case side of 43mm and are fitted with a fluted bezel, the sign of an exceptional Montblanc timepiece.

The Lime Gold version displays green hands and numerals and comes on a green alligator leather strap with grey stitching that is in total harmony with this warm-coloured gold. The stainless-steel edition features a white gold fluted bezel, adding an extra level of finesse to the model, and comes with a blue alligator leather strap with blue stitching.

Both models feature an engraved caseback with an image of the Villeret manufacture and the famous “V”-shaped mountains in the background.
