This new official chronograph from Porsche comes with both a Pvd-coated steel strap and an interchangeable rubber strap, both in black. The movement is a RONDA 5040.D with 13 stones, while the three-part casing is constructed from Pvd-coated stainless steel in black and with side inserts made of carbon. The watch’s dial is also carbon-fibre and it's covered in sapphire glass with an anti-reflection treatment. Waterproof up to 10 ATM, the casing measures 42mm and includes a limited-edition serial number engraving on the base. Swiss made with just 911 copies in the series, you can grab yours from the official Porsche shop at www.porsche.com for £900.
