Where most GMT timepieces indicate the second time zone with an additional hand, the Montblanc 1858 GMT presents its GMT indication without hands that is very intuitive and highly legible. The Montblanc 1858 GMT indicates the second time zone with a red square that moves around the outside of the dial. This red square is positioned next to a fixed blue anodized aluminium bezel with a 24-hour clock. This system also indicates the half hours. Other functions include a date and central seconds. The timepiece is housed in a 42mm stainless steel case and comes with a blue sunray dial and a tapered interchangeable stainless steel bracelet with fine adjustment for precision fitting. An engraving on the case back shows the continents, oceans, and names of cities in each of the 24 time zones, offering a worldtime indication.
