Add to Wish List

The Montblanc 1858 Collection continues to reinterpret the famous Minerva chronographs from the 1930s, with distinct designs and exceptional mechanics that traverse time. The vintage style of the collection has been further enhanced by the introduction of bronze—a first for the Maison. Through this choice of metal, Montblanc combines traditional Swiss artisanal watchmaking with a genuine material from watchmaking history. The 1858 Chronograph Tachymeter Limited Edition 100 showcases a vintage style—from the design of the case, to the movement, strap and details on the dial. The timepiece comes with a champagne dial that has a sunray finish to match the bronze color of the case. This combination of colors and finish gives a monochrome and mono-material aspect to the timepiece, accentuating the timepiece's volume and drawing attention to the details, such as the historic cathedral-shaped hands and beige Super-LumiNova® markings that accentuate the vintage style while also providing excellent readability at night. This limited edition is housed in a 44 mm fully satin-finished bronze case with a bronze-colored titanium case back (to avoid allergies) and polished bezel for increased depth. At the heart of the timepiece lies a traditional manual monopusher chronograph movement, the caliber MB M16.29, which is entirely handcrafted at the Montblanc Manufacture, with a column wheel mechanism, horizontal coupling, chronograph bridge in a "V" shape, large screwed balance wheel vibrating at a frequency of 18,000 semi-oscillations per hour and power reserve of 50 hours. For the first time, the large "pocket watch" style caliber bears rose gold-colored components that offer a totally new look and perfectly match the bronze material and vintage appeal of the timepiece, while also reinforcing its monochrome aspect. For utmost reliability and performance, the timepiece has been rigorously tested by the Montblanc Laboratory Test 500.
