Montblanc has released a new limited-edition model of the 1858 Split Second Chronograph that originally debuted at the 2019 SIHH show.

The numeral indexes, the cathedral hour and minute hands, and the tachymeter and telemeter scales are finished in green. Interestingly, the green Arabic numerals are fully made of Super-LumiNova.
