Harrods customers will have their first chance to get their hands on the Roger Dubuis Excalibur Spider Pirelli collection this week.
The watches, which go on sale from August 1, are the product of a partnership between tyre-maker Pirelli and the Richemont-owned Swiss watchmaker.
Pirelli engineers were involved in the straps, which are made from motorsport tyre rubber.
The watches also use a black and blue, red or yellow skeletonised flange, the colour coding used to distinguish different grades of tyre used in motor racing.
The colours are also carried through to titanium black DLC crowns and matching stitching on the straps.
Only 88 models are being made this year for the whole world.
