he Kalparisma is an elegant and sleek timepiece with a unique aventurine dial and diamond frame. Aventurine glass was invented by mistake in Murano (Venice), Italy, in the 19th century when an artisan glass blower accidentally let drop copper particles into the molten glass. The result was this fine material, whose name derives from the Italian expression “all’avventura” – i.e., “by accident.” The Kalparisma family has a specific characteristic: the small seconds at 6 o’clock, with a star that spins around every minute. Both a decoration and a horological complication, inspired by a pocket watch in Maurice-Yves Sandoz’ collection, which was restored at Parmigiani Fleurier’s atelier workshop.
