TAG (Techniques d'Avant Garde), manufacturers of high-tech items such as ceramic turbochargers for Formula One cars, and British businessman Ron Dennis, acquired Heuer. In 1999 TAG Heuer accepted a bid from LVMH Moët Hennessy Louis Vuitton S.A. of CHF 1.15 billion (£452.15 million, USD 739 million), contingent upon a transfer of 50.1 percent of stock. In 2010, TAG Heuer introduced the "Pendulum Concept", the first magnetic oscillator without hairspring capable of providing restoring torque comparable to that of hairspring. In 2013, TAG Heuer celebrated the 50th anniversary of the Carrera, the racing-inspired chronograph that is a key part of the TAG Heuer range today. There have been ten generations of Carrera since its introduction, with models launched in every decade since 1963. In 2017 TAG Heuer released limited edition Muhammad Ali watch. Motto and slogan A company slogan of TAG Heuer is "Don't Crack Under Pressure". The slogan was originally introduced in 1991. Watch manufacturing Watches TAG Heuer's current lines include Formula One, Aquaracer, Link, Carrera, Monaco, Connected, Autavia, and Heuer Heritage. Some of the more recently announced models include the Monaco V4 (the movement of which is driven by belts rather than gears); the Carrera Calibre 360 (the first mechanical wrist chronograph to measure and display time to 1/100 of a second) and the Monaco 69 (with both a digital chronograph accurate to a millisecond and a traditional mechanical movement, with a hinged mechanism allowing wearers to flip the watch between its two separate dials). London-based Christoph Behling has been the lead designer for TAG Heuer since 2004. The collaboration has resulted in some of the brand's most celebrated pieces including the world's fastest chronograph, the Mikrogirder 1/2000th, launched in 2012. Many TAG Heuer watches feature chronographs. In January 2011 TAG Heuer announced the new Carrera Mikrograph, the first TAG Heuer to use the in-house Mikrograph movement, which is accurate to 1/100 of a second. Additionally, TAG Heuer has also released the limited edition Carrera MP4-12C to commemorate the launch of the McLaren MP4-12C supercar. TAG Heuer has been a partner of the McLaren F1 team for over 26 years. At the Basel 2011 show in March 2011, TAG Heuer announced the Mikrotimer Flying 1000, a concept mechanical watch capable of accuracy of 1/1000 of a second—ten times faster than the Mikrograph. This mark was superseded in January 2012 with the Mikrogirder model, precise to 5/10,000ths of a second.
