Cartier ID One Concept Watch


IDone Concept Watch

Cartier introduces a concept watch without adjusting!
La Cote des Montres - November 29th, 2009

Indeed, thanks to an innovative conception requesting breakthrough materials and technologies, this concept watch does not need the usual adjusting components of mechanical movements:
  • conceived as a mono-bloc piece and manufactured in carbon crystal (material allowing the use of a micron engraving technology), the balance-wheel is directly well balanced
  • calculated to obtain an optimum chronometry and manufactured in an innovative material called Zérodur®* (material allowing the use of a micron engraving technology), the active length of the hairspring is directly adapted to the balance-wheel
  • manufactured in carbon crystal, the anchor and the anchor wheel are perfectly matching at the time of assembly

Moreover, this concept watch remains perfectly adjusted throughout its lifetime thanks to:
  • a carbon crystal escapement cage mounted on silent-blocks (true shock-absorbers of the movement) which protect all the regulating components (hairspring, balance-wheel, anchor, anchor wheel, escapement axis),
  • a manufacturing of all regulating components in materials insensitive to thermal variations and magnetic fields (balance-wheel, anchor and anchor wheel in carbon crystal, hairspring in Zérodur®*, axis in titanium),
  • movement components with a very low friction coefficient. Indeed, they are either coated with ADLC, either manufactured in carbon crystal: this coating and this material do not need liquid lubrication (oil or grease)


Adjusting: a major know-how in mechanical watchmaking


TTraditionally, a mechanical watch’s movement requires several adjusting operations done by a master watchmaker. These adjusting operations are mandatory to ensure the good functioning of the watch.

As soon as the watchmaker starts assembling the watch, he needs to operate several adjustments:
  • Make the balance-wheel perfectly balanced, either with adjusting screws, either by removing matter on the rim
  • Adjust the hairspring with the balance-wheel by modulating its active length, most of the time using an index assembly
  • Ensure a good match between the escapement components (anchor and anchor wheel), by modifying the position of the adjusting pallet-stones on the anchor.

In some situations the movement might get misadjusted: in case of shocks or magnetisation, when there are strong thermal variations or when the oils get too old or dried. If this happens, the movement has to be re-adjusted.
