LEO HOULDING: LINDE WERDELIN

British climber Leo Houlding has taken his Linde Werdelin watches to the depths of the Amazon, across ice caps and up the highest mountains, but perhaps nothing filled him with more adrenaline than his introduction to the Queen at Buckingham Palace in 2011. As a pioneer of para-alpinism, Houlding was the first Briton to free climb El Capitan in Yosemite, California and, in 2019, he scaled Mount Roraima in Guyana with his LW Spidolite Monochrome.
