The Hublot King Power 'Red Devil' Manchester United Limited Edition ref. 716.OM.1129.RX.MAN11 is a very special watch as part of the watch features DNA from the actual Old Trafford stadium. If you look closely at the hour markers ??these applied elements are a bit green in tone as they are actually made of the famous grass from the MU stadium. As part of their continued efforts innovating and developing new materials and components, Hublot experimented with how to do this and finally came up with a process that involves freeze drying and then lacquering segments of the grass, making them almost look like "sod crystals."
