The Haddon CLD was part of the second generation of CLD (sealed) watches. It's quite a bit larger than the first generation Langdon - which is the closest comparison. It was produced for only two years and two different dial arrangements were available; either a AGN dial or a luminous marker dial.
The Haddon has a two piece case with a pop-off front bezel and a case back with integrated lugs. Like most CLD models, the Haddon's 8/0 sized 747 movement is held in the case back and is pulled out the front when the bezel is popped off. It uses a two-piece stem, since there's no access to the back of the movement while it's in the case.
I have found that many of these 2nd generation CLD's typically wear okay and any wear through you're likely to find will be on the reverse, near the crown. I don't know why that is but I bet it occurs at least half the time.
As received, my Haddon was in typical shape. It was quite dirty but nothing a thorough cleaning wouldn't take care of.
I'm not sure if the bracelet on it is original to the watch. It could be or maybe it's just a very close likeness. I usually put straps on my watches but I kind of like the way this one looks with it's bracelet... original or not.
