Montblanc kicked off its year of new releases earlier this Spring, rolling out new models in its Heritage and Star Legacy collection. Now, as one of the 30 watch brands rolling out new timepieces as part of the Watches & Wonders online platform, Montblanc unveils new blue-dialed versions of two complicated models in its vintage-influenced 1858 collection.

The Montblanc 1858 Split Second Chronograph Limited Edition 100 features a 44-mm case made of grade 5 titanium and a graduated blue dial made of grand feu enamel. Based on a military chronograph produced by the heritage watchmaker Minerva (now part of Montblanc) in the 1930s, the dial hosts two classically designed scales: a telemeter scale, used to measure distance based on visible and audible phenomena ? i.e., to calculate how far away a storm is based on the time between a flash of lightning and the first rumble of thunder, and the snail-shaped tachymeter scale in the center for measuring the speed of a moving object over a known distance. Both scales employ the watch?s built-in chronograph function, operated by a monopusher in the crown; the chronograph is also equipped with a ?rattrapante,? or split seconds device, operated by an additional pusher at 2 o?clock. Orange details, such as on the central chronograph hand and the minute scale’s numerals, as well as white on the scales and subdials, and a beige-colored elapsed seconds hand, provide contrast with the blue dial.
