The Grandmaster Chime took an astonishing 8 years to develop, and contains 20 complications made up of 1,366 parts. Two of the complications were actually the first of their kind. The price tag on this 18 karat rose gold hand engraved masterpiece was a whopping $2,500,000. Only 7 watches were created, one of which is in the Patek Philippe museum. The other 6 were immediately sold, which makes chances of seeing one of these babies slim to none.
