EDOX VISION AND MILESTONES
1884
One year earlier, a very romantic Christian 
Ruefli-Flury, a highly talented watchmaker 
“Maître-Horloger” from Grenchen in 
Switzerland, builds a pocket watch for the 
25th birthday of his beloved wife Pauline. 
Impressed by the accomplishment of her 
gift, she convinces then her husband to 
set up his own watch making company in 
Biel in 1884, a famous city for its well-
educated watch engineers. Christian 
Ruefli-Flury calls his company “Edox” 
which means “the hour” in ancient Greek.
1900
The hourglass is officially used as a time-
less symbol for Edox and is since a proud 
heritage part of the early years of the 
company.
1921
After the death of the founder, the com-
pany is taken over by Robert Kaufmann-
Hug, a wise businessman. He quickly 
makes decisions which change Edox des-
tiny in propelling the company as the first 
watch making facility producing wrist 
timepieces only.
1955
After World War 2, demand for Edox time-
pieces continues to grow. Edox employs at 
that time up to 500 watchmakers. The 
company moves into new, larger and 
modern production facilities. The high-
tech machines allow the production of 
highly water-resistant timepieces.
1961
It is the year of birth of the famous “Delfin” 
timepiece. This Edox invention features for 
the first time of the watch industry a dou-
ble case back, sturdy protective gaskets 
and seals that set new standards of shock 
protection and water resistance.
1963
The Edox “Hydrosub” timepiece is 
launched featuring the first crown system 
with tension ring and shock-absorbing 
gasket allowing a waterproofness of 
500 meters. The “Hydrosub” timepiece is 
still nowadays well known for its avant-
guardiste technical achievement.
1970
The early 70’s witnesses the introduction 
of the world’s first truly universal time 
watch, the Edox “Geoscope” timepiece. 
Covering all time zones, the watch pro-
vides the hour of almost 50 different cities 
around the world as well as the wearer’s 
local time.
1983
After a worldwide financial recession, the 
company is taken over and is since a 
family-owned independent company. The 
decision is made to move the facilities to 
Les Genevez in the heart of the Swiss 
Jura, the homeland of many famous 
highly skilled watchmakers.
1998
Edox engineers and watchmakers develop 
a superb invention: the world’s slimmest 
watch with calendar, the “Les Bémonts 
Ultra Slim” collection. The movement has 
a height of only 1,4 mm. This technical 
record is held unbroken by Edox since 
then.
