Luxury watches are difficult things to produce in large numbers. Not only do they take a long time to make, but there are only so many people in the world capable of making them. The value of a watch is defined not only by its mechanical complexity and the quality of the materials used in its construction, but by its scarcity, too, which is why MR PORTER always strives to present the best selection of exclusive and hard-to-find watches. Think of them as future heirlooms.
