Sorry, I didn´t told what I was exactly thinking of but I was looking forward to your brainstorms.
In the rough I dreamed about a clock same sized as the SAS-compass or even smaller. So Frankie´s idea (Jaeger-LeCoultre Calibre 101) was keenly what I´ve thought but my budget seems to be too limited for it and I believe it is a sacrilege to burry such a genius item down in my PSK.
I´m even sad because I love full mechanical things over all electronics.
I think I´ll focus on xbanker´s Wal-Mart theme (Yes, they´ve finally reached Germany).

Thanks to all of you
Molf
