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.
During the 2013 Masters, Woods faced disqualification after unwittingly admitting in a post-round interview with ESPN that he had taken an illegal drop on the par-5 15th hole when his third shot had bounced off the pin and into the water. After further review of television footage, Woods was assessed a two-stroke penalty for the drop but was not disqualified. He finished tied for fourth in the event. Woods won The Players Championship in May 2013, his second career win at the event, notching his fourth win of the 2013 season. It was the quickest he had gotten to four wins in any season in his professional career.
World Golf Championships-CA Championship: Logged 56th career TOUR victory and 13th official World Golf Championships title in 24th start at the CA Championship at Doral Golf Resort & Spa. Held the 36- and 54-hole leads before closing out a two-stroke win over Brett Wetterich, marking the 39th time winning (in 42 events) when holding at least a share of the third-round lead.
In the days and months following Woods' admission of multiple infidelities, several companies re-evaluated their relationships with him. Accenture, AT&T, Gatorade and General Motors completely ended their sponsorship deals, while Gillette suspended advertising featuring Woods. TAG Heuer dropped Woods from advertising in December 2009 and officially ended their deal when his contract expired in August 2011. Golf Digest suspended Woods's monthly column beginning with the February 2010 issue. In contrast, Nike continued to support Woods, as did Electronic Arts, which was working with Woods on the game Tiger Woods PGA Tour Online. A December 2009 study estimated the shareholder loss caused by Woods's affairs to be between $5 billion and $12 billion.
