1858 Geosphere 0 Oxygen 44 mm, titanium with black textile strap, self-winding manufacture caliber MB 29.27 with chronograph function and date display | Reference Number MB000058

Let's climb the summits! Featuring an ultra-light titanium case, the 44-millimeter 1858 Geosphere 0 Oxygen Chronograph (Ref. 130811) is a strong and uncompromising companion. Its self-winding manufacture caliber MB 29.27 requires no oxygen at all and, in addition to the date, reliably displays a 30-minute and 12-hour counter as well as the world time on its rotating northern and southern hemispheres. Visually, the design is also convincing all along the line: Thanks to the gratté boisé technique, the anthracite dial looks as if it has been frozen over with a layer of ice. The bidirectional black ceramic bezel also indicates the cardinal directions for good orientation in the open country. An elaborately engraved caseback, a power reserve of up to 46 hours, and a limitation to only 290 watches worldwide make this model a sought-after mountaineering watch.
