“The decisive factor is the timing of Baselworld at the end of April, which cannot be reconciled with our scheduling,” Breitling Chief Executive Officer Georges Kern said in a statement on Sunday. He said his company will decide later whether to resume exhibiting at Baselworld in 2021.

Kern has previously questioned whether it’s worth the money to attend Baselworld, the world’s largest watchmaking trade show, saying last month that the Geneva watch salon and Baselworld should be be merged into one and be held earlier in the year.

Baselworld, run by MCH Group, which operates convention centers in Zurich and Basel, is feeling the heat. The number of exhibitors is declining as watchmakers reconsider whether it’s worth attending and debate the need to use such events to sell their product. MCH Group’s shares have fallen 15 percent this year, after slumping 70 percent in 2018.

Swatch Group CEO Nick Hayek said last month he has no plans to return to the Baselworld watch fair in coming years.
