Woods was raised as a Buddhist, and he actively practiced his faith from childhood until well into his adult, professional golf career. In a 2000 article, Woods was quoted as saying that he "believes in Buddhism... not every aspect, but most of it." He has attributed his deviations and infidelity to his losing track of Buddhism. He said, "Buddhism teaches me to stop following every impulse and to learn restraint. Obviously I lost track of what I was taught."

Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005. The lightweight, titanium-construction watch, designed to be worn while playing the game, incorporates numerous innovative design features to accommodate golf play. It is capable of absorbing up to 5,000 Gs of shock, far in excess of the forces generated by a normal golf swing. In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.
