The introduction of a new GMT movement able to simultaneously keep the time in two time zones takes this heritage one step further. Yet the MBIII very much retains the classic DNA that has made the MB a must-have for any serious collector. It has been put through the same intensive, extensive testing schedule that includes shock, vibration, temperature extremes, and salt-fog tests.
