Cosmic 2000 Bracelets

So I've come into possession of this Cosmic 2000, with no real information on the age or history other than that it was amongst the watches my grandfather had for fixing.

It's running fine and keeping good time, but the bracelet has been really abused:

There's a few links that are really destroyed, and the rest are either coming apart or really roughed up. I don't know anything about this bracelet, but I'd like to replace it, and I was wondering if anyone would know what type it is and how available it might be.

Thanks all - I'll have to keep an eye out for the 1171, and see what the cost of a 1171/1 is.

I may have some 677 end links in my parts box if you can find a bracelet.
