Another luxury brand is jumping into the smartwatch game. Hublot has announced that it's making a limited number of its first smartwatch -- an extension of its Big Bang line that's all about the 2018 FIFA World Cup. While World Cup referees will wear the watch, consumers will be able to buy it as well, though the company says it's only making 2,018 of them. The smartwatch will announce World Cup matches 15 minutes before they begin and will update wearers on yellow and red cards, player changes and goals. Game statistics will appear on the watch face while play is ongoing.
