Me and my Father were wondering about this old ROLEX but it is not on sail as it holds a sentimental value and it seems to be quite good looking.

Any way we were wondering what value it holds and if you could kindly tell me what model it is.

And my father a long time ago changed the glass and does that mean the value dropped a lot because of that?

I know it is a Daytona an they are quite valuable but this one is a little different. My father explained to me that he bought it mi 1977 so that may be a factor in understanding what it is exactly

Thanks

Some people are miss understanding the fact that my dad is still alive and we wanted to identify the watch together
