On 6th July, for the launch of the Swatch Scuba Libre collection, we invited UK bloggers to set sail on a journey aboard a Central Line train branded especially for the new collection... we didn't tell them that this journey would be anything but ordinary. We surprised the bloggers with an a cappella choir, dressed in scuba-diving gear, performing 'Underwater' (by Mika) from the 'Mad About the Sea' Scuba Libre TV commercial.
