Chronographe Nicolas Rieussec
Available in the Star Legacy Collection
The Montblanc Nicolas Rieussec shows the time in two different time zones at a glance: the owner's home
country time and the local time in their present location. A window display tells them whether it is day or
night in their home country, while another aperture shows the date. Short periods of time can be measured
on the two rotating counter discs with the help of two fixed pointers.
The MB R200 calibre features a rotor fitted with a heavy metal weight to maximise its winding efficiency.
It supplies energy to two barrels, which provide 72 hours' continuous running. The chronograph is
controlled by a traditional column wheel, which defines the positions of the levers and activates the start,
stop and reset functions. With its high moment of inertia and a frequency of 28,000 vibrations per hour
(4 Hz), the large screwed balance wheel delivers an extremely stable rate.
