My dad bought this pocket watch years ago but does not know anything about it. We took it to the IWC boutique as South Coast Plaza and while they were very intrested in it, they too knew nothing about it.
Does anyone here know anything about this watch?
Well, without at least a pic of the movement, even better movement number und case number, information that can be provided is limited.
What I can say from your pic it is so-called dress watch from presumably the 1930ies with a calibre 73 (or maybe 97).
Don't care too much about the word "Chronometre". In these days there existed no legal defiinition and so everybody could print CHRONOMETER on the dial (and so did IWC), who deemed his watches of above average quality.
