Stepping up in Montblanc's range
The 1858 GMT takes an unconventional approach to its second time zone display: rather than a traditional GMT hand, a red square travels around the outer edge of the dial beside a fixed black anodised aluminium bezel marked with a 24-hour scale. The system accommodates half-hour zones as well as full ones. The black sunray dial carries Arabic numerals and hands treated with Super-LumiNova, while a domed sapphire crystal with double anti-reflective coating sits above. The titanium caseback is engraved with the Earth's continents, oceans, and the names of 24 cities. A quick-release black rubber strap with fine adjustment completes the package.

Learn more about Montblanc
Montblanc was founded in Hamburg in 1906 as a fountain pen manufacturer, and the six-pointed white star that marks its products represents the snow-capped summit of the mountain. It entered watchmaking in 1997, initially as a luxury accessory line.
That changed decisively in 2007, when Richemont transferred the Minerva manufacture in Villeret to Montblanc. Minerva, founded in 1858, was one of the great chronograph specialists — it had produced its own monopusher chronograph calibres since 1908, including movements capable of measuring to a hundredth of a second, and had continued making them by traditional methods long after the industry mechanised.
Montblanc inherited that capability along with the tooling, archives, and watchmakers. The Villeret and 1858 collections now house Minerva-derived calibres with their distinctive devil's tail chronograph bridges, screwed balance wheels, and hand-finished components — genuine high horology at a house most people associate with pens.
The volume side of the business, produced at Le Locle, covers the Heritage, Star Legacy, and TimeWalker lines, and the 1858 Geosphere with its twin rotating hemisphere globes has become the signature model.
Montblanc has also pursued smartwatches through the Summit range and remains part of Richemont.
