Visitors to Montblanc’s split-level boutique on the rue de la Paix are greeted with a chandelier studded with 630,000 Swarovski crystals and a gorgeous array of limited editions and one-of-a-kind pieces, from high jewellery and luxury leather goods to timepieces manufactured in the Swiss village of Le Locle. The Salons Privés, a cluster of private rooms on the top floor, create an intimate setting in which to explore the jewellery collections.
