25 March 2015 11:58 am / 4 comments The partnership between IWC Schaffhausen and Mercedes-AMG is 10 years old this year, and to celebrate, the Swiss luxury watchmaker has unveiled the new ‘AMG GT’ edition of its Ingenieur Automatic – the world’s first watch to have a case made of pure boron carbide – at the Goodwood Members’ Meeting. Limited to 25 pieces, the watch pays tribute to the Mercedes-AMG GT sports car, both in name and design. The multi-piece watch case is made from ceramic boron carbide – one of the hardest and most scratch-resistant materials known to man. The black and yellow references the AMG-exclusive colour ‘solarbeam’, while the rubber strap features yellow lock stitch seams and a black inlay of Dinamica micro-fibre, as found on the steering wheel, seats and headlining of the Mercedes-AMG GT.
