Nobody is buying Swiss watches anymore apart from the 'astonishing' French

The Swiss watch bubble might be about to unravel.

After years of stunning growth, in which exports more than doubled from 2000 to 2014, Swiss watchmakers had a terrible month.

China led the fall, according to export figures from the Federation of the Swiss Watch Industry.

Overall exports were 9.3% lower than a year earlier, at 1.9 billion Swiss francs (£1.3 billion) with the Chinese market segment dropping by more than 39%. Sales to the United Arab Emirates also tanked 29.8%.

Weirdly, watch sales to France jumped more than 50% in July. The Federation doesn't have an explanation for that, just calling it "astonishing."
