It's a win-win. OMEGA's brand values are all about it being the watch of choice for pioneers and explorers. This is a great way to reinforce their brand in an authentic way. What's Rolex doing, golf tournaments?
I kind of thought watches are dead. But granted, if you are an explorer, you might not have the opportunity to charge your iPhone, so a watch might be of use.
In tennis now Rolex has been completely eclipsed by Richard Mille, which I'd guess most people hadn't even heard of until Rafael Nadal started wearing one. Their brand is really taking a beating now, it can't be helped by Wiley writing songs about it. Be interesting to see what they do to dig themselves out of this hole.
