The first grande complication wrist watch certainly were the IWC Destriero Schafusia, and the Blancpain 1735. In the article,
It is said that the watch has to be a grande et petite sonnerie...
Which is correct.
The problem is that the term " Grande Complication " has been hackneyed by the brands marketing teams, and that nowadays, you can see, with a bit of surprise, that a simple perpetual calendar is called " Grande Complication "...
A pity...
