Your one-minute primer to the Rado DiaMaster Power Reserve.

Here is a watch that feels as good as it looks. With a 43mm case made of polished black or plasma high-tech ceramic, which is five times more scratch resistant and 25 per cent lighter than steel, its hypoallergenic surfaces adapt readily to one's skin temperature for a more comfortable wear. Its distinctive blue or black dial, marked with a sunray pattern emanating from the centre, is further characterised by an oversized power reserve indicator that hints of the mechanical prowess of its automatic movement that is able to drive the watch for 80 hours on a full wind.
