Regarded as one of the greatest Formula One drivers of all time, ‘Magic Senna’s’ talent and panache is beautifully represented in this TAG Heuer Formula 1 Ayrton Senna Quartz Special Edition watch. TAG’s loyalty to Ayrton Senna is still as strong as it was when he became the face of their very first #dontcrackunderpressure campaign in 1991, shown through its stunning design inspired by the adrenaline filled world of motor racing. The TAG Heuer quartz movement found within its core is made exclusively in Switzerland and meets an extremely strict criteria to ensure it delivers only the best in precision and longevity. With a sleek 43mm stainless steel body and ceramic fixed bezel, this TAG Heuer Formula 1 watch provides an elegant aesthetic just like that of the race car driver that inspired it. The striking anthracite grey sunray dial is beautifully detailed with Superluminova coated hour and minute hands, three black and yellow subsidiary counters and a date window at 4 o’ clock. Each of these handy functions are powered by a Swiss quartz movement which is kept hidden behind a circular screw-in case back decorated with a special Senna engraving inspired by the Formula 1 race track. To complete the look of this TAG Heuer Formula 1 Ayrton Senna watch, a stylish fine-brushed bracelet is added alongside a folding clasp fitted with a special extension especially designed to fit over a racing suit.
