The new Tourbillon 24 Secondes Vision is as discreet as it is refined. Those main new products presented at the SIHH 2015 integrate an inclined tourbillon which stands into a hole done through the caliber. It is so deep that a curved micro sapphire glass was applied on the back. 
The "Vision" model includes a new, slimmer and smoother case, which is less discreet than the majority of Greubel Forsey pieces. The dial is marked by indexes made out of enamel, which is quite rare in high-end watchmaking nowadays. 

The two other new products are both declinations of the GMT with its massive rotative globe inside. The 5N one consists of a main plate and bridges coated with a luminous red gold. The Black watch's case is made out of titanium and coated with ADLC. Its sporty and chic touch could be a watch that Batman would gladly bring on a mission.
