SIHH 2013 Preview part two: Lange und Soehne, IWC and Greubel Forsey

Today, the SIHH 2013 opened its doors, and 16 manufacturers offer their latest models and innovations. In part 2 we present the latest from Lange und Sohne, IWC and Greubel Forsey.


The famous Glashutte brand is offering a few new models. The Grande Lange Lume 1 was already announced earlier, but celebrates today its official presentation. The semi-transparent dial exposes the ingenious mechanism of the first luminescent outsize date display watch. The hidden interior is now shown to its proud wearer. Furthermore, the 1815 Rattrapante Perpetual Calendar shows another variation on the 1815, already a classic since 1994.A_Lange_Sohne_GRAND_LANGE_1_Lumen-2

IWC shows the world that  they are official partner of the Mercedes AMG Petronas Formula One team with a new addition to the Ingenieur line, the Ingenieur Chronograph Racer. Already familiar with AMG as a sub-model range, the Chronograph Racer adds As  a “omnicompteur” ,that can time up to 12 hours as well as the pit stops to give the average speed over a distance reference. A whole new movement  (caliber 89361) was created to facilitate a chronograph display measuring more than minutes.


The Ingenieur Chronograph Racer can be had with a carbon case.  The whole collection can be seen on

Greubel Forsey shows the  Double Tourbillon Technique Black. It is the first black model by Greubel Forsey, featuring a titanium case and rubber strap, elements that “endow this three-dimensional chef d’oeuvre with more casual aesthetics than the classic gold and platinum models.”  Admittedly, the timepiece looks absolutely stunning!


 The second premiere is the Double Balancier, which shows a regulating system comprising of two inclined oscillators and escapements. They are driven through a spherical differential, which provides the average of their rates via the gear train to the time display.


The timepiece is an further evolution of GS’s ground-breaking research into inclined oscillators, resulting in a prototype in 2009, showing amovement with two inclined oscillators, each at 20°. Today’s premiere brings two inclined oscillators spatially disposed in different three dimensional planes. A marvellous timepiece, which further establishes the reputation of Greubel Forsey. We cannot wait to examine the watch more closely.
