|The Montblanc 1858 Automatic Chronograph was introduced at SIHH 2018. It pairs the vintage aesthetics of the 1858 collection with a self-winding Sellita-based chronograph movement, the latter significantly lowering the price compared to other chronograph watches in the collection. The case measures 42mm across at a height of 14.55mm.Reference 118223 has a bronze case with a titanium case back with bronze coating, and a smoked champagne dial. It is fitted with a cognac-colored aged calf leather strap.
