Hi, there. I am looking to find the watch brand for this case. I received this as a heir loom from my grandfather and I remember that it had a blueish oister dial as a child. I know it was made sometime in the 70's and all I can go by is the insignia on the crown. I would love to find the brand so as to bring this watch back to life. I appreciate your help and or ideas. I will be looking for a dial as well as its movement mechanism once I am able to establish the make.
