PHILADELPHIA — Switzerland is used to being alone. It’s not a member of NATO or the European Union; it eschews the euro in favor of its own currency, the Swiss franc, which has lately gained value against the euro and the dollar.

The whipsaw week for the Swiss horologist, as U.S. President Donald Trump slapped a surprise 39% trade tariff on imports from the European country, underscores how businesses big and small are being forced to adapt and rejig operations under pressure.

The White House previously said they would issue an executive order clarifying tariff levels on the precious metal this week.
