The 3448 could also have been produced with four dial variations that presented four series. It is not clear if the dates of production and details on the dials which distinguish them from each other have been agreed upon. The only thing that can be said is that the first dials were made of hard enamel, while the later dials were printed. It is difficult to talk about the series with so many contradicting details. This calls for further exploration of the 3448, including unique pieces like the platinum pieces and a piece in yellow gold with a blue dial.
