IWC Schaffhausen presents the Portuguese Sidérale Scafusia, the most exclusive and complicated watch ever created by IWC.

After ten years of intensive research, the Swiss watch manufacturer has succeeded in combining solar time with sidereal time in a single watch.

Every watch is unique

The Portuguese Sidérale Scafusia will not go into series production. Every single watch will be produced exclusively to order by the customer and is an individual project in itself. Since the star chart and horizon as well as sunrise and sunset times have to be calculated and displayed for a precise location specified by the customer, individual mechanical parts have to be custom-manufactured, then assembled and adjusted individually.

This means that every customer is not only wearing a unique watch on his wrist but also his own personalised constellation of stars, as seen in the night sky from the location of his choice. With the Portuguese Sidérale Scafusia timepiece, individuality is of the utmost importance. As part of a special service, customers can design their own precious watches within the limits set by IWC’s design philosophy.

The range of case and strap materials, together with the choice of five different colours for the dial as well as various colours for the appliqués and straps, results in over 200 possible combinations. In view of this individuality and the highly demanding design work involved, buyers will have to wait approximately one year for delivery. But as we said: special features require time.
