Junghans Watch Meister Mega 58/4503.46. The Meister MEGA from Junghans is not only precise, it is also easy to use. The movement is automatically time-synchronized every day. If you travel to a different time zone, the time can be set using the crown either in hourly increments or using the stored time zones - without losing the precision of the seconds. In addition, every wearer outside the transmitter areas has the option of setting the watch to their own individual time using the Junghans MEGA app.
