I like Ronan Keating a lot and here is Oyester Perpetual Cosmograph, which is worn by him. The watch reads time and calculates average speed. The watch is self-winding and waterproof to 100 metres/330 feet.

The watch is not very playful however has professional and elegant handsome looks. The price of the watch is not known.
