Apple has reportedly paid £13 million ($21 million) for the Swiss clock design used in iOS 6.

Apple introduced the new clock design with iOS 6 for iPad (above left) in September, but it was met by complaints from the Swiss national rail operator SBB, who designed the clock in 1944 and has used it in train stations across Switzerland since then.

The design, which was once honoured by the Museum of Modern Art in New York, was licensed to Apple on 13 October, but the terms of the agreement were not disclosed.

A story from news agency AFP (Agence France-Press) says that 'US tech giant Apple has dished out 20 million Swiss francs (£13 million) to compensate Swiss national rail operator SBB for using its famous clock without permission', citing Swiss daily newspaper Tages-Anzeiger.

Mondaine, a company that has had a long-term exclusive licensing agreement to adapt the design of the Swiss Railway Clock watches and clocks for consumers (above middle and right), says it was "surprised" about the agreement, but that "Apple shows great taste by choosing this design for their clock on their devices, and now, the owners of Mondaine watches and clocks as well as iPad owners can even enjoy the same distinct design."
