The organiser of Geneva's international expo of fine watches said Thursday it had decided to cancel the April event because of the spread of the deadly new coronavirus.
"In view of the latest developments concerning the worldwide spread of the COVID-19 coronavirus... the decision has been taken to cancel the upcoming edition of Watches and Wonders Geneva," said the Fondation de la Haute Horlogerie.
The announcement came as more than 2,700 people worldwide have died of COVID-19, and almost 80,000 have been infected, mainly in China.
Switzerland reported its first case this week, and by Thursday the number of cases had grown to five, including one in Geneva.
The Fondation de la Haute Horlogerie said that "in order to protect the health and wellbeing of all our guests, press, partners and teams" it had decided to cancel the event, due to have taken place from April 25-29.
The event is a major trade show for the luxury watch industry and is particularly important for the many Switzerland-based makers of fine timepieces, particularly Richemont brands like Cartier, Piaget and Jaeger-LeCoultre.
The event, which is typically held in January, had already been postponed this year to coincide with Baselworld, another massive watch fair held in the northern Swiss city of Basel in April.
The organisers of the Basel event told AFP they were "evaluating the situation in extremely close coordination with Swiss federal and regional authorities."
