Hello Kathy. It sounds like you have a nice watch on its original bracelet. From what you described, it is not a "premoon", but, the second of four generations to follow the premoons. (Those would be "transitional", "first on moon" (which is what you likely have), calibre 861, and calibre 1861, which is the current generation today. There are also a few more subtle distinctions within some of the generations, such as dial variants, but for the purposes of this discussion, those are not important.)
The value of a good condition, working, original, but honestly-used first on moon watch is probably in the ballpark of $3,250 USD. Again, pictures here will help us tell the story.
When servicing or repairing your watch, most collector (and sentimental) value comes from originality: this means keeping original dial, case, hands, bezel, and if possible crown and pushers. It is generally considered acceptable, even amongst the hardest of the hard-core originalists, to replace a crystal (the "watch glass"), particularly if cracked. There is no concern with replacing the movement parts (the mechanical parts of the engine that runs the watch), because you need these parts to be at their best for your watch to last for generations. But the parts you touch and see - the case, the hands, the dial, the bracelet, the crown...these are the parts (even if faded, worn, chipped, or slightly less than perfect) tell the story of the first 50 years your dad and watch had together, and will continue to tell the story of the next 50 amd more you and your family will have going forward!
Welcome!
