That was the logo of the John Wanamaker department stores, the signature you mention. Sadly, the brand is defunct, now part of Macy's. The flagship store on Market St. in Phila. has a huge Wurlitzer organ on one of the upper floors, still featured in concerts.
I'm very much looking forward to this watch...I think the multicolored dial is gorgeous, it's all-steel and a nice 36mm, and it will the only one of my chronographs with a telemeter scale (which would have been useful in all those thunderstorms we had in Chicago last week!).
