Abhishek Bachchan's loyalty to the brands he endorses seems unquestionable. The actor dug into his Omega collection for a vintage watch to wear in his forthcoming period film "Khelein Hum Jee Jaan Sey".

Abhishek, who was appointed as the face of Omega in India in 2006, has worn a black leather strap watch from the Swiss brand throughout the film.

"Abhishek had a piece from the independence struggle period in his Omega collection, so he decided it would be appropriate to wear it, " said a source close to the actor.

The 34-year-old plays a freedom fighter in Ashutosh Gowariker's "Khelein Hum Jee Jaan Sey", based on the Chittagong uprising of 1930s. The film releases Friday.
