Known amongst collectors as the "Ferrari Carrera", the 18K yellow gold model reference 1158CHN was gifted by Jack Heuer to Ferrari drivers. As part of his sponsorship, famous drivers such as Niki Lauda, Clay Regazzoni, Jacky lckx and Mario Andretti received this watch. History tells us that Jo Siffert was also gifted this reference as "Brand Ambassador". This particular watch is an earlier production version with an harmonious black calendar window, which succinctly balances the 12 hour subsidiary register and 30 minute counter. This particular example also features the original "small hole" Heuer Corfam strap and unusually, an 18K yellow gold sun buckle as opposed to the more standard gold plated version. This rare and precious watch is offered today in fantastic condition. The hallmarks remain crisp, the caseback sticker is intact and the burnished brush finish to the case superbly complements the warmth of the champagne colored dial. The perfect balance between Heuer's sporty DNA and the elegant and dressy look conveyed by the yellow gold case make this watch the perfect fit for any occasion.
