The first shop listed the Polar Vantage V and Vantage M.
The dutch online shop bijvoetsport.nl listed both new Polar watches.
The Vantage M costs 280€ and the Vantage V 500€. Please note that the Netherlands have a VAT of 21%. So the prices might differ in other countries.
Unfortunately it is not clear if the watches are in black or white. Also there are no information about different sizes.
EDIT: The publication seems to be a mistake. All articles are no available in the shop anymore.
