These developments follow last week's reports of luxury brands, including Dior, Celine, Hermès, Louis Vuitton and Saint Laurent, being targeted by looters during demonstrations across several French cities.

Pandora has confirmed that three of its stores – two in Paris and one in Lyon – were vandalised and looted during the unrest. All three locations remain closed, and the company has implemented additional security measures, including boarding up windows and temporarily closing stores, to protect its premises and employees.

Breitling CEO Georges Kern has told reporters the Swiss watchmaker is prepared to close its stores if further demonstrations threaten staff and property.

These incidents highlight the increasing challenges facing jewellery and watch retailers as the protests continue to disrupt commercial activity. Previous reports also raised concerns that stolen luxury merchandise has entered resale platforms and black markets, further complicating the industry's efforts to verify product authenticity and provenance.

The French Chamber of Commerce estimates that 2,400 stores have been damaged nationwide, with losses to retailers exceeding €1 billion. With further demonstrations planned for 31 October and 5 November, retailers are facing continued uncertainty, particularly as November and December typically account for around 40 per cent of France's annual retail turnover.
