IWC has released their donation to the Only Watch auction coming up on November 7, 2015. The unique piece Ingenieur Automatic Edition “Tribute to Nico Rosberg” features a 46 mm case made of solid boron carbide, one of the hardest and most scratch-resistant materials available. The timpiece is powered by a IWC caliber 80110 mechanical movement with Pellaton automatic winding system, fitted with a blackened rotor. Completing the ensemble is a unique rubber strap with Dinamica inlay accented and green quilted stitching – the same innovative microfibre used in the Mercedes Benz AMG GT interior.
