With the Minerva Unveiled Secret and Geosphere 0 Oxygen Montblanc have been on an absolute tear when it comes to haute horology and cutting edge technology. Which just makes it all the more exciting when they turn their attention to more widely available complications such as a GMT function. Their new take on the classic traveller’s complication in the form of the Montblanc 1858 GMT Automatic Date features a handless design that’s as striking as it is intuitive.
The 1858 GMT Automatic Date has a 42mm stainless steel case with a polished and knurled aluminium crown and a titanium caseback. The combination of lightweight, durable materials help give it a sporty vibe ideal for long distance travel. The same is true for the fixed aluminium bezel, which features a 24-hour scale.
That scale forms a central part of the titular GMT function. However, instead of using the traditional GMT hand to point to the second time zone, Montblanc have implemented a handless system. It functions by having peripheral apertures that show a red square which corresponds to the bezel’s 24-hour scale. Plus, between each of the square hour windows is a rectangular window that represents the half hours, giving you a greater degree of accuracy. Stylistically it’s similar to the handless date function on the Nomos Glashütte Neomatik 41 Update.
Speaking of style, the GMT Automatic has two to pick from. There’s a blue dialled version or an alternative in black. Both have sun brushed dials and matching tone bezels that enhance the sporty aesthetic of the case. On the reverse side, the titanium caseback is laser engraved with a world time display and an image of the Earth. It provides a handy reference for setting the GMT function and can also be customised to include your hometown and its local time.
Inside, the GMT Automatic houses the automatic calibre MB 24.33. It has a 42-hour power reserve and features central hours, minutes and seconds alongside the peripheral handless GMT display. It may not be mechanically on par with Montblanc’s other new releases, but it might be the most wearable.
