Need advice for potential Tudor sub purchase...

[buddy13]

Ok there is a nice tudor sub for sale locally. I am intrigued ...but I know little about these watches so would need some help/advice...

The watch is the one pictured and comes with all boxes/papers, tags, anchor etc...It comes with 2 original Tudor bracelets and is a one owner watch bought new in 2000. It was serviced once by a reputable local watchmaker



Now onto some questions:

1) What is the correct model no. for the watch please?

2) I really hate the shiny bezel insert. Is it hard to find a replacement black one? What would the cost be?

3)Is this watch somewhat rare/sought after (Easy to move it on if I do not like it..)?

4) What is a fair price to pay for the watch?

I sincerely thank you in advance for any advice !
