A number of “Swatch” stores from London to New York had to close Saturday, all because the frenzy over a new watch.

“The Royal Pop Collection” is a collaboration between Audemars Piguet and Swatch. Surging crowds prompted last-minute closures at stores over safety concerns. That included the Swatch locations in Soho on Spring St., Roosevelt Field on Long Island and at 17 other stores nationwide.

Prices for the watches range from $400 to $420 each.

Audemars Piguet watches typically go for anywhere from $20,000 to well over $1 million each. But the company says this collection is not a limited edition.
