Watches of Switzerland can eye strong earnings ahead, UBS says, raising its rating on the U.K.-based retailer's stock to buy from neutral. The group can look to rising demand for luxury watches among U.S. consumers, as well as a strong brand mix and a position in a fragmented retail landscape, UBS says. Together, that proves "scope for further earnings upgrades and rerating," the Swiss bank says, lifting its target price on the London-listed stock to 850 pence. Shares are up slightly at 732.5 pence.
