Microworks delivers two key components for IWC Schaffhausen’s new Portuguese Sidérale Scafusia timepiece
On August 27, 2011, IWC Schaffhausen presented its new masterpiece, the Portuguese Sidérale Scafusia, at the European Southern Observatory in Paranal, Chile. One of the newly designed features of this exclusive watch is a constant-force tourbillon. "Using x-ray LIGA technology enables the fabrication of parts with sub-μm precision", explains Pascal Meyer (KIT/IMT), who originally adapted the fabrication process to make watch parts for IWC Schaffhausen. Thomas Gäumann, head of the R&D department at IWC Schaffhausen, adds, "Parts of the escapement are precision made to one-thousandth of a millimetre—I reckon that was no mean feat." The timepiece is described in detail on the IWC Schaffhausen website (http://www.iwc.com/en-us/collection/siderale/) and in an article by Elizabeth Doerr (http://www.worldtempus.com/en/news/top-news/detail/article/1314981578-iwc-astronomically-complicated/).
