Catalogue Note

This model, Ref. 3940, was launched in 1986.

The present example is from the first series of this model and features a dial with no crossed leap-year indicator, a standard, non-deployant buckle and only one, solid case back.

It is believed that there were about 1300 of these models made from this series, and, as it was only made in such a variation for about two years, it is more rare than subsequent series.
