We usually like things big, take our Square Extreme watch - we went big. but there are some things that we don't like big, big bills, big queues and big negative numbers. here's a number for you 780 million, would be nice with a £ or $ at the beginning right? but what if we told you that was the figure (taken from water.org) of the number of people that lack access to safe water?

That's why during the whole of March 2015 we're donating money from every sale to water.org.

780 million people – about one in nine or to put it another way that's around 12 times the UK population – lack access to safe water; 2.5 billion people lack access to a toilet. Water.org is dedicated to changing this. Through sustainable solutions and financing models such as WaterCredit, we can provide safe water and the dignity of a toilet for all.

Founded by Gary White and Matt Damon, Water.org pioneers innovative, community-driven and market-based solutions to provide access to safe water and sanitation -- giving women hope, children health and communities a future. To date, Water.org has positively transformed millions of lives around the world, ensuring a better life for generations ahead.
