TAG Heuer's collection of watches reflect the notions of innovation, precision, performance and glamour. This brand offers instruments that are accurate to 1/10th, 1/100th and 1/1000th of a second for wristwatches, and to 1/10,000th of a second for timekeeping. TAG Heuer was founded by Edouard Heuer and his sons Jules-Edouard and Charles-Auguste in 1860. The entrepreneurship had a strong spirit of innovation, a passion for achieving ultimate precision, and a deep love of prestigious sports. These central characteristics established by the brand's founding fathers continue to epitomize TAG Heuer today. The lines include Formula One, Aquaracer, Link, Carrera, Monaco, and others. Most models feature automatic (self-winding) mechanical movements, water resistant cases, and sapphire crystals; some pieces also include sapphire case-backs, enabling wearers to view the movement's inner workings.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 1/100th 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).The brand's rich history that begun in the late 19th Century and continues in the present day indicates a commitment to an exceptional product. TAG watches continue to succeed in satisfying their wearers.
