What is “micro”?


Micro is defined as extremely small.

But what does this mean in reference to micro-components? When seen at a human scale (above) and then closeup (left) you gain some perspective of what “micro” means to Audemars:

  • A micro-ceramic assembly less than 4mm in length with two precisely positioned micro-coils (Ø 1.2mm)
  • A micro-rotor with a gold coated micro-magnet (Ø 1.4mm) laser welded to a precise pinion in a fully automated process
  • A micro-coil (Ø 0.5mm) wound using 10 micron wire (note: human hair ≈ 100 micron!)
  • A micro-magnet disk (Ø 0.5mm x 0.19mm) executed in Sm2Co17 or cylinder (Ø 0.22 mm) executed in NdFeB

These are just some of the many examples of the small things that make a BIG difference when you trust Audemars with your micro-component needs.
