Montblanc has added three new watches to the Heritage Chronométrie collection that introduces a fresher, more contemporary design code. The “Chronométrie” in the name of the collection is derived from the French word for “precision,” thus the new watches include solid horological credentials despite their affordable price tags. The latest additions to the collection includes two new interpretations of the patented ExoTourbillon Slim which was launched back in 2016. The first watch in this new collection is the Montblanc Heritage Chronométrie Perpetual Calendar Sapphire (ref. 118513), which features the same movement as the 2014 perpetual calendar. The 2018 edition comes with a new 40mm stainless steel case with slimmer lugs, a fully polished finishing and new dial design. The perpetual calendar indications are featured on transparent counters that are in a shade of dark-blue color. The watch is priced at EUR 12,700 (roughly $15,000).
