Here are some pics of the watch opened....does this help to identify it? ...  

I inquired about a similar but not quite the same watch in December last year and got help from one very kind fellow collector. He could not quite help me to track the history of my watch but he could document the history of your watch. What I learned was...  

Your GP watch is really sharp looking! Thanks for sharing what you know about my watch...
