The watch you see here is 47mm in diameter, made using the new technique of Direct Laser Sintering, which allows for the case to be extremely light (the movement only weighs 23 grams). Direct Laser Sintering is the 3D printing of .02 mm layers that are welded together to create a full form. The movement used is the manual-winding P.2005/T, which Panerai’s in-house movement used in the previous Lo Scienziato skeletonized watches. The new laser process allows for the watch to weigh 35% less than the P.2005/S movement. Additionally the sapphire crystal case back allows you to see the movement and power reserve (which is 144 hours).
