A strange case from our workshop: this Jaeger le Coultre Reverso has a "bug" which is very evident but indeed very difficult to guess at first look. You can test your skill in the watch field. It has to be remembered that the watch has not been altered by us and is exactly in the same state it was when it exited the factory.

The bug should be clear, now. You can ask for the "mystery" to be revealed using our contact form, anyway.
