*UPDATE* – it looks like Polar have registered polarvantage.com so this will likely be the teaser site like we saw with polarv800.com previously. For early information and teasers, check there regularly. Note that Polar are in Finland so updates are likely to be timed accordingly. That said, they do use agencies for these teaser sites which may be based elsewhere.
Well, it looks like we finally have a name. Or rather two names. Thanks to Cardiojunkie for the tip. Also reading comments on TFK it would seem that these are round watches with one being higher end than the other.
