I've been looking at this watch for a while now, and waiting for Android wear 2 before pulling the trigger on an S3 Frontier.
Wear 2 made little difference to my LG Urbane and found this deal.
The included Gear Fit 2 is worth around £180 alone. If you were to sell the Gear 2, this bring the price of the S3 down considerably.
Samsung are doing various 2 for 1 deals,well worth a look.
Top Cash back currently doing 4% on Samsung products, which is worth the best part of £14 on this deal.
