The Astronomia Sky is a £538,000 watch made by luxury watch brand Jacob & Co.

With only 18 being produced worldwide and costing more than half a million pounds, it's a very rare and expensive watch - so what makes it so special?

Jacob and Co watchmaker, Luca Soprana says: "The Astronomia is a very, very delicate piece. Every component needs to be perfectly balanced so we need to use very special materials - like titanium - that are very delicate. The idea is really to come with a watch that is three dimensional and the watch has to be spectacular."

"What really makes the piece special is really the technique. The complexity of how it works, and to have an equilibrium of all the components."

The face of the watch intricately replicates the movement of the celestial map.

It's an impressive looking watch, but at £538,000 it's ridiculously expensive.

If you had the money would you buy it?
