There were a number of similar Polerouter Day-Date models made in the late 1960's to early 1970's. Here's another one: from Polerouter.com Hope this helps, gatorcpa
Thank you.I was not familiar with the brand until recently when I came across this unit. My guess is the day and date combination were not so common
I am not overly on love with this watch.I was trying to identify on order for me to figure out if is worth keeping and putting some money on a band, cleaning dial.etc.Hoping it grows on me but its not a square face nor a diver nor Russian which are my favorites
