I've posted some instructions here before on the Carrera Twin, but that doesn't have an alarm so doesn't really help you - I remember Timothy posting something about the alarm on his Verona that might be of help.

The gold-plated buckle should still have the little "sun" and "Swiss" markings, but will say "PLAQUE G" instead of "ACIER INOX".

The layout should be the same as this (borrowed a pic from a post by Abel), but with the changed text at the left.
