Chopard Tech Twist Sincere edition

For sale very rare (I saw it only twice available on the secondary market in the last two or three year) Chopard TechTwist. This is limited edition of 100 for Sincere.  It has Sincere insignia on the crown and very unusual blackened movement. The movement is Chopard’s in-house 3.96 automatic microrotor movement marked as 96TB. The 42mm stainless steel case does not have any scratches or marks. The watch comes with the original Chopard alligator strap showing minimal wear and original double fold deployant buckle.  Both boxes and all the papers are included.  I am asking $6800 for the watch.  The price includes PayPal fees and shipping charges. I prefer to sell the watch within continental US, but am willing to discuss international deals.
