These have been out for a while but somehow I hadn't seen them before. Swiss company Sarcar has found a way to add yet more diamonds to a watch. In their Solitaire watches a bezel set one carat diamond rotates around a dial set with a carpet of diamonds. The watch comes in red or white gold and the bezel and dial are set with brilliant-cut diamonds and the crown features a diamond. The watch has a crocodile leather strap and there is also a limited edition Royal Solitaire watch with a gold and diamond set strap. The standard Solitaire will cost you around six figures.
