Martin Braun EOS - With sunrise & sunset indication

The EOS is the first mechanical watch to be manufactured with the ability to indicate the time of sunrise and sunset, and is named after the Greek goddess Eos (originally Eos or Avos), a deity representing the dawn. When ordered, the clock is set individually according to the buyer's place of residence and according to the longitude and latitude, so that the correct reading of the sunrise and sunset time is possible. EOS models are made to order and there is a choice of colours for the sunrise and sunset discs.
