Patek Philippe unveils a new self-winding grand complication that combines its exclusive dual time zone "Travel Time" system with a 24-hour alarm mechanism, complete with a hammer that strikes on a classic gong. To do so, the manufacture has developed an entirely new integrated movement, registering four patents for the alarm in the process.
