Junghans Meister MEGA

The Junghans Meister MEGA, the watch created by the designers in Schramberg, is equipped with a state-of-the-art radio controlled movement developed by the company’s in-house engineers. The design follows the tradition of the Meister line. A balanced dial with harmonious proportions bears witness to the elegant style of the timepiece. The continents depicted on the watch are an indication that the Meister MEGA is at home in the world.

The new J101 radio-controlled movement of the Meister MEGA guarantees absolute precision everywhere. The basis for this is four years of development work and the radio control technology know-how acquired over the course of over three decades. The movement as a whole comprises a total of 146 components, which are tested to the strictest precision criteria. For example, the plate is tested at 1,462 measuring points to an accuracy of 5 micrometres. This accuracy in production is also reflected in the accuracy of the watch.

On three continents the time is received via a time signal with a deviation of just 0.006 seconds in one million years. If the watch is outside of the reception range, it continues to run automatically with the accuracy of an especially precise quartz movement – with a maximum time deviation of 8 seconds a year.

The ITC technology (Intelligent Time Correction) ensures that the position of the second hand is compared with the most recently received time information 1,440 times per day – and adjusted when necessary. Even greater accuracy comes from the SHM technology (Smart Hand Motion), which ensures that the watch is even more precise, thanks to the half-second steps of the second hand. In addition, the movement of second and minute hands and the changing of the date are triggered a fraction of a second before the time change – for the most accurate display of the actual time. The wearer can rely on correct date changing at all times, as the display also shifts automatically from the last day of the month to the 1st day of the following month when the watch is in quartz mode, or when there are 30 or fewer days in the month.

The Meister MEGA from Junghans is not just precise, it is also convenient to operate. Time synchronisation of the movement takes place automatically every day. When travelling to another time zone, the time can be adjusted via the crown, either in hourly steps or by using the stored time zones – without losing the precision of the seconds. In addition, wearers also have the option of setting the watch to their individual time when outside of the reception areas, using the Junghans MEGA App.
