Description

RETROGRADE SYSTEM

This lightning fast retrograde system is based on three key elements: a central axis set in ruby bearings ; a cylindrical marine chronometer type spring running vertically around the axis; a double coaxial star-shaped cam regulating the retrograde mechanism.

POWER RESERVE INDICATORS

The 48-hour power reserve is indicated in the upper left and right corners, featuring two hands moving across two scales. This power reserve distributed on two sub-dials is made up of 83 components, testifying its complexity of development.

OIL CHANGE SERVICE INDICATOR

The oil change indicator keeps a running track of how long (in months) the movement has been in operation.


CARBON CASE

The ultra-light case is made of 81 layers of CTP Carbon, compressed in a resin. These extremely thin layers (thickness : 0.15mm) are made to resist the onslaught of time. The carbon structure draw on the UR-220 a refined frame which underline the profiled shape of the case.
