Montblanc Displays its World Time Geosphere in Bronze

To celebrate the 160th anniversary of Minerva, its historically iconic watchmaking heart, Montblanc is releasing a limited edition watch as part of its 1858 collection.
Reading time 2 minutes

Marked countless red dots on two curved hemispheres of the dial, the theme of this limited edition watch is the seven highest peaks in the world. These are also engraved on the back of the Worldtimer Geosphere's case, alongside the silhouette of Mont Blanc and two crossed axes, setting the tone. The universal time complication, the brainchild of Montblanc Villeret's engineers, sits under a sign of the spirit of conquest and innovation. This model features two rotating, curved hemispherical globes, which make a complete turn every 24 hours.

World Time

Powered by a self-winding caliber, the northern hemisphere rotates counter-clockwise while the south operates clockwise. A scale of the 24 time zones circles both, with day and night both visible through contrasting colors. To increase readability in the penumbra, the longitude reference meridians have a white line treated with Super-LumiNova, reflective of the continents. The second time zone is displayed at 9 o'clock, while the date, corresponding with local time, appears at 3 o'clock. The display is complete with a bidirectional, bronze fluted bezel with ceramic inserts of engraved cardinal points. A luminescent beige index and Arabic numerals, domed cathedral needles, a railway timer, and a bronze box all add to this unique watche's vintage style. This limited edition has 1,858 pieces, which corresponds perfectly with the year the Minerva factory was developed. 

Technical Details

The watch features a 42-millimeter bronze case, as well as a rotating crown with a ceramic insert. It has anti-reflective sapphire crystal, a titanium bottom, and is waterproof up to 100 meters.  Montblanc's self-winding mechanical movement has a 29.25 caliber, and is certified "Montblanc Laboratory Test 500." The power reserve lasts 42 hours, and the bracelet is cognac calfskin, with a triple folding clasp in bronze-treated steel.
