CERAMIC ENDSTONE FOR THE TOURBILLON CAGE This reflects a technical and long-term view towards the elimination of wear phenomena, resulting in improved technical tribology. TORQUE LIMITING CROWN MAIN FEATURES (MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS) This additional security system prevents from accidental overwinding, which could cause damage to the winding stem or putting extreme pressure on the mainspring barrel. The crown is set with precious stones or semi-precious stones depending on the version. POWER RESERVE BARREL PAWL WITH PROGRESSIVE RECOIL Circa 48 hours. This function is displayed using a newly designed differential power reserve system, with a printed red line on a moving disc located between 10 and 11 o’clock. This device permits a profitable winding gain (circa 20 %), especially during the winding start. It is also helpful in the distribution of the mainspring’s internal tension. MOVEMENT OTHER FEATURES Two creatures adorn its precious movement, writhing and searching within the tourbillon movement, whilst simultaneously holding the precious tourbillon movement in place. We can admire a ruby & diamond encrusted 18k white gold snake and an emerald & diamond encrusted 18k white gold snake with red coral tongue. But there are several other versions available of these coupled snakes, such as precious stones encrusted or semi-precious stones encrusted, or engraved stones, and even enameled bodies. Each model is an unique piece. It took many hours and extremely precise work to engrave by hand the scales of these two exceptional jewellery pieces.
