Wow thats a no brainer price. Go grab it!
clove.co.uk does one better I believe. £799 for the Sony Xperia 1 II with a free Sony WENA Wrist Pro and a free WENA Wrist Mechanical Head, both in silver.
According to clove.co.uk, the recommended retail cost of this combination is £474 and the offer is subject to stock availability.
