4810 ExoTourbillon Slim

Montblanc 2016

ref. 114864
Men's

For its 110th anniversary, Montblanc turns the spotlight on its 4810 collection, including this ExoTourbillon which completes the brand's patented complication with an instantaneous stop-seconds function. The ExoTourbillon is so-named because it separates the tourbillon cage from the balance wheel, which in this instance measures a respectable 9.70 mm in diameter. The off-centre micro-rotor allows a clear view of the movement and does not add additional height to the calibre, at 4.50 mm. Seconds are shown by an arrow on the tourbillon cage. When the stop-seconds function is operated, only the balance is halted rather than the entire tourbillon cage. The different crown positions of setting, winding or stop seconds are shown in a gauge on the dial.
