World’s lightest watch created using graphene

Scientists have developed the world’s lightest high-performance mechanical watch RM 50-03 made using the ‘wonder material’ graphene. The RM 50-03 watch weighs just 40 gms.  The ultralight watch was made using a unique grapheme composite known as Graph TPT incorporating graphene to manufacture a strong but lightweight new case to house the delicate watch mechanism. It was jointly developed by the University of Manchester (UK), Richard Mille and McLaren F1.  Graph TPT weighs less than previous similar materials used in watchmaking. Graphene is the world’s first 2D material at just one-atom thick. It was first isolated in 2004 and has the potential to revolutionise a large number of applications including high-performance composites for the aerospace and automotive industries, as well as flexible, bendable tablets, mobile phones and next-generation energy storage.
