Like on the original timepiece, the Montblanc 1858 Split Second Chronograph features a telemeter scale that runs around the dial, which was a typical feature on the legendary Minerva chronographs. A telemeter makes it possible to measure the distance of a phenomenon which is both visible and audible, like the lightning and thunder in a storm.
The timepiece also features a tachymeter (base 1000) at the centre of the dial in a colimaçon, snail shape, which allows the user to measure a length of time up to three minutes instead of one minute in a traditional chronograph scale around the dial.
It is combined with a complex “rattrapante” (split second) complication developed by the Montblanc engineers that allow the user to measure intermediate times without interrupting the ongoing measurement of a longer elapsing time. The “rattrapante” can be admired through the sapphire glass of the case back like on traditional timepiece with such a function.
