Bulova 1969 International

Hello, please find attached the pictures of my Bulova watch. I have not been able to identify my models from those being presented at this site.  A note on the date 1969: In order to fill out the form I had to specify a manufacture year. I have no idea in which year my watch has been manufactured, which is why I typed in "1969" just to be able to save the watch and upload the pictures. I hope that you can help me to find out the correct manfuacture year. On the dial following information can be found: "Bulova = Automatic = 23 Jewels = T Swiss T" (reference to tritium?)  The outer backcase has the following number stamped on it: 1-773595| - The crown has a "Bulova" relief. As to the watch´s background: I bought it from a flea market in Germany in 1995. The watch has not been opened ever since, but it still works immediately and with high accuracy. Since I do not have the right tools and there is no watchmaker where I live, I unfortunately can´t show you any pictures from the movement and the inside backcase. This is really all the information that I can give you. I am not interested in selling the watch. I am looking forward to every bit of information that you could share with me. Thank you very much in advance.

Best
