MICRO-ROTOR
FBN Calibre 229.01
- Self-winding mechanical movement
- Diameter: 14″ (31.60 mm)
- Thickness: 4.35 mm
- Frequency: 3Hz (21,600 vibrations/hour)
- Number of jewels: 34
- Power reserve: 80 hours
- Indications: hours, minutes, seconds with stop-seconds function
- Micro-rotor between bridges
The micro-rotor winding system is off-centred and placed between two bridges. It is secured by two jewels to ensure excellent stability. This reduces the movement thickness and ensures a clear view of the construction.
- Pawl-fitted micro-rotor
The unidirectional automatic winding with pawl-fitted micro-rotor system is closer to the principles of traditional horology and above all ensures greater long-term efficiency.
- Double direct-impulse escapement fitted directly
on the balance
This new boasts a silicon lever. This modern construction, combined with the use of cutting-edge materials, maximises energy efficiency, which in turn ensures high amplitude for the balance and reduces the mechanical force need to wind the mainspring.
- Balance spring

- Barrel
Barrel mounted on two jewels to enhance efficiency.
- Shock-absorbing system
Shock-absorbing system for the micro-rotor.
- Oscillating micro-rotor
