For a man who spent nearly three decades in prison, the passage of time was no doubt important to Nelson Mandela.
That's why it's perhaps fitting a new exhibition opening in London features the late South African president's watch.
(SOUNDBITE) (English) GRANDSON OF NELSON MANDELA, MANDLA MANDELA, SAYING: "My grandfather during his presidential years, he wore a watch, a Philippe Patek watch and I've made that watch available because he gave me that watch and I think because he was such a committed person and always on time and always upheld time and he was never late for any commitment, even when he travelled abroad his watch remained on South African time which we found hilarious as a family, but that watch is also here on display." The interactive exhibition takes visitors on a journey through Mandela's life - from his upbringing in rural Eastern Cape as the son of a chief To his 27 years in prison on Robben island and the end of apartheid when he became South Africa's first black president in 1994.
Mandela died in 2013 at the age of 95.
For his grandson, the exhibition is an important tribute to the life and legacy of Madiba - as he was also known.
"Madiba may no longer be with us, but the fight continues.
We need to champion the work that he represented.
He was a global icon for justice, peace and fought for human rights, and we need to take the stand to speak out." London is the first city to host the touring show before it is permanently mounted in Mandela's birthplace - the small village of Mvezo.
