The Grandmaster Chime 6300 is a wristwatch from Patek Philippe.

This is the most complicated Patek Philippe wristwatch. It unites 20 complications, including five chiming modes, two of which are patented world firsts: an acoustic alarm that strikes the preselected time and a date repeater sounding the date on demand.

Its development, production and assembly requires an incredible 100,000 man-hours.
