Swiss luxury watch brand Ebel is offering a five-year international unconditional guarantee on all its watches—the longest offered by any company in the watch industry, it says.

To celebrate the new warranty, which took effect in April, Ebel is issuing a special version of its 1911 model, named for the brand’s founding date, in two limited editions: the Golden Five, an 18k automatic (five units); and the Silver Five, a stainless-steel quartz model (1,500 pieces). The numeral 5—”a symbol of harmony and balance,” says the company—appears on each as an appliqué on the black dial.
