IWC Sidérale Scafusia

A watch with a price tag of 750.000 dollars is sure to be spectacular, especially when developed and produced by the modest company IWC.

The Sidérale took over 10 years to develop and employed both professors and epic independent watchmaker. It is easy the most complicated watch ever made by IWC. It also their competitor to the Skymoon tourbillion from Patek that I blogged about earlier.

At 46 mm diameter and 17.5 mm thick the Sidérale is quite the bulky piece. The front of the watch displays time, a huge constant force tourbillion at 9 o’clock, sidereal time at 12 o’clock (a time-keeping system astronomers use to keep track of the direction to point their telescopes to view a given star in the night sky.) and a 90 hour power reserve at 4.30.

The caseback of the Sidérale is so complex it brings shivers. It combines a perpetual calendar with leap year display and absolute day of the year, with a celestial chart showing horizon, ecliptic and celestial equator with a indication for day, night and twilight, with a display for sunrise and sunset and coordinates for a specific location.

You won’t see many of these around and that’s why you should get it. Check out the in-depth video by Hodinkee below.
