Caroline-Marie Scheufele recalls a rule growing up that on Sundays, any dinner table conversation about the family business attracted a CHF5 (Swiss francs) fine. “And my sister, who invented the fine, collected a lot of money, I can tell you.”

The family business is Chopard, the Swiss watch and jewellery brand founded in 1860. Caroline-Marie’s grandfather, Karl Scheufele III – himself a third-generation goldsmith and watchmaker – bought it from Paul-André Chopard in 1963.
