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.
Following an outstanding junior, college, and amateur golf career, Woods turned professional in 1996 at the age of 20. By the end of April 1997, he had won three PGA Tour events in addition to his first major, the 1997 Masters, which he won by 12 strokes in a record-breaking performance. He reached number one in the world rankings for the first time in June 1997, less than a year after turning pro. Throughout the first decade of the 21st century, Woods was the dominant force in golf. He was the top-ranked golfer in the world from August 1999 to September 2004 (264 weeks) and again from June 2005 to October 2010 (281 weeks). During this time, he won 13 of golf's major championships.
