Hey guys i'm new to this vintage watch community and am still learning the ropes. Recently my parents gave me an amount to spend on a watch. So i have been looking at a poor man's heuer for some time and found this watch on ebay and was super excited as it was within my budget. Without much thought i bid on it and thought it was a steal. But after scrutinising the watch more, i found the movement is not signed and i could not find any picture of this particular model of hamilton on the internet. So please give me your expertise on this matter.
Thanks for your time
