Montblanc Heritage Spirit Orbis Terrarum UNICEF
The central sapphire disc shows the Earth’s northern
hemisphere as seen from the North Pole. The second disc
indicates the passage from day to night, passing through
dark blue, yellow and green shading. On a ring, this same
disc shows the names of the 24 cities representing the
24 time zones. The local time of the city facing the red triangle
at 6 o’clock is read on the central hour and minute
hands. The times in the different time zones can be read
simultaneously from the 24-hour ring around the outside
of the dial.

Jaeger-LeCoultre, Geophysic Tourbillon Universal Time
The central disc, which shows a polar projection, rotates
in 24 hours, taken on its journey by the flying tourbillon
with its Gyrolab balance wheel. The carriage of the latter
rotates upon itself every minute, while the orbital tourbillon
completes one rotation in 24 hours –symbolising the
starting point of our 24 time zones, which are indicated
on a concentric ring encircled by the day/night indicator
of the 24 hours. All its functions are adjusted using the
single crown.
Andersen, 25 years of world time
In 1990, Sven Andersen presented his first ‘World Time
Watch’ in tribute to the eponymous watch by Louis Cottier.
He produced several successive iterations of it: the
Christophorus Colombus, the Mundus and the 1884. In
2015, he once again commemorated Louis Cottier, presenting
a ‘worldtimer’ with two crowns, as developed by the
genius watchmaker. Finally, to mark the 25th anniversary
of his World Time watches, Andersen has just released the
Tempus Terrae 25th Anniversary. 25 pieces in white gold.
The central disc has a magnificent luminous guilloché
pattern with concentric scales in blue gold, symbolising
the planet on which we live. The watch is adjusted using
the two crowns, one setting the hours and minutes, the
other the time zone.
Girard-Perregaux, WW.TC Perpetual Calendar
The exclusive combination of 24 time zones and a perpetual
calendar – relating to the home time – was premiered
in 2006 by Girard-Perregaux as part of its WW.TC collection,
standing for World Wide Time Control, an appellation with
greater ‘Wall Street’ appeal than the simple ‘World Time’. A
moon phase rounds out the numerous indicators on the
beautifully balanced, 41mm-diameter dial.
