In 1991, the JUNGHANS MEGA was the world's first radio-controlled wristwatch designed as an analog watch . To distinguish it from the digital variant Mega 1 , it is also referred to as JUNGHANS MEGA 2 .

General

description

The MEGA 2 has a partially gold-plated stainless steel case. The white dial with two gold hands and a rectangular LCD display is protected by a circular, scratch-resistant mineral glass. The antenna for receiving the DCF77 time signal transmitter is housed in the brown leather strap with a folding clasp .

Technical specifications

The MEGA has an integrated radio receiver with a wrist antenna to receive time signals with the long wave frequency of 77.5 kHz.

The caliber is a quartz movement of the type w605 with a quartz time base of 32 kHz and a light barrier for hand control. The energy supply comes from a lithium button cell with 3 V operating voltage.

At 2:00 and 3:00 a.m., the time is synchronized with the time signal transmitter in Mainflingen . If there are reception problems, the comparison is repeated every hour on the hour until 6:00 a.m.

history

In 1985, the German watch manufacturer Junghans brought the first radio-controlled table clock onto the market. In 1990 the engineers of this company succeeded in miniaturizing this technology to such an extent that it fit into the case of the digital wristwatch MEGA 1. In 1991 Junghans launched the analog variant MEGA with pointers.
