About the watch
MatErIaLS
TiTanium for The middle-case
The single-piece middle-case
is made of titanium. This
metal is both lightweight and
resistant, making it the ideal
material for an exceptional
watch.
Titanium is also very
corrosion-resistant and has
thus been used in the AP case
back and folding buckle.
chromaTised aluminium and ceramics
borrowed from the automotive and aeronautics
industries, these materials have pride of place in
the royal oak concept gMT Tourbillon.
The bridges are in nickel silver with all-black
galvanic finish and the flange is black-chromatised
aluminium. These anodising processes increase
hardness and improve resistance to friction.
research work in another field led to the development
of innovative ceramics. for the bezel, crown and
pushpieces, Audemars Piguet selected a ceramic
material with very specific physical properties.
The ceramic has undergone particularly delicate
treatments calling on all the knowhow of the
Manufacture’s engineers and watchmakers. The
essential qualities of
this technical ceramic
are its tremendous
resistance to friction
and wear and its
exceptionally smooth
final finish.
