Two names for a great adventure

n  1875,  two  young  men  passionate  about 
Haute  Horlogerie  —  Jules-Louis  Audemars  and 

Edward-August  Piguet  —  decided  to  pool  their  skills 
to  design  and  produce  watches  with  complications 
in  the  Vallée  de  Joux,  the  cradle  of  Haute 
Horlogerie.  Determination,  imagination  and  
discipline  led  them  to  instant  success.  A 
branch in Geneva was their next move in about 
1885  and  new  commercial  links  were  forged 
at  the  1889  Paris  World  Exposition,  where 
they  exhibited  complication  pocket  watches. 
The  Audemars  Piguet  factory  continued  to 
expand  as  the  years  went  by.  Its  creations 
represented  major  milestones  in  the  history  
of  Haute  Horlogerie,  like  the  first  minute 
repeater  wristwatch  in  1892  and  the  smallest 
five-minute  repeater  movement  ever 
made in 1915.

From  1918  onwards,  the  founders 
passed  the  reins  of  the  business  onto 
their  sons,  who  in  turn  perfected 
their  expertise  in  manufacturing 
men's  and  ladies'  wristwatches  as 
well  as  designing  new  sophisticated, 
ultra-thin  movements.  Perseverance 
and  initiative  were  the  watchwords :  while  the  Wall 
Street  crash  in  1929  was  a  bitter  blow,  the  company 
directors  were  soon  designing  so-called  skeleton 
watches before embarking on chronograph production. 

But  this  new  momentum  was  abruptly  interrupted  by 
the  Second  World  War.  Re-organisation  was  necessary 
in  the  aftermath  of  the  conflict.  The  factory  focused 
on  creating  top-of-the-range  items  in  keeping  with  its 

tradition  of  innovation.  A  strategy  that  would 
prove  its  worth,  especially  since  it  was  backed  
by outstanding creative daring. 

Audemars  Piguet  continued  to  build  on  
its  now  international  reputation  with 
creative  designs.  1972  saw  the  launch  of  
the  Royal  Oak,  the  first,  immediately 
successful  high-quality  sports  watch 
in  steel,  followed  in  1986  by  the  first 
ultra-thin  tourbillon  wristwatch  with 
automatic  winding.  The  creative  spirit  of 
the  Manufacture  has  not  faltered  since, 
offering  aesthetically  original  time- 
keepers  with  outstanding  movements. 
Thus it brought watches with complications 
back into fashion at the end of the 1980s, 
launching  its  extraordinary  Tradition 
d’Excellence  collection  in  1999.  All  the 
signs  of  a  bold  spirit  rooted  firmly  in 
tradition and auguring well for the future.
