Swiss watchmaker Rado will be the official time-keeper for the Chennai Open ATP tournament, the company said on Thursday.
Indian tennis star Rohan Bopanna launched Rado's Hyperchrome Collection, which would also be the "official watch" of the tournament to be held from December 31 to January 6.
Bopanna, who will team up with US-based Rajeev Ram for the Doubles event, said, "I am starting a new season right now and am coming back to Chennai in a couple of days to play in the tournament."
Bhopanna is pairing up with Ram after the recent decision by him and his partner Mahesh Bhupathi to play with different partners in 2013.
Bhupathi and Bopanna had won two titles at Dubai and Paris and a runner-up finish at the just-concluded season-ending London Masters.
BopannaÂ attained his career-best ranking of eighth in March.
