Alarm watches triggered my interest in collecting vintage watches, as well as divers.
My first vintage alarm watch is an Angelus Datalarm which I have hidden somewhere. Since I already had a Panerai, the association of Panerai with Angelus was something that attracted me toward the small Datalarm, which I named βmy little Paneraiβ.
The alarm complication seems a romantic one. I enjoy being awakened by a mechanical alarm watch. I also like to interrupt a meeting that has gone too long just to say: sorry! I have to call my wife, and leave the room 
Anyway, enjoy your Panerai when it gets home, of course.
Cheers.
