Please be aware that this is what "price guide" says about condition:

condition is assumed to be excellent or near mint; not New Old Stock (NOS) or mint, but a very fine example; dial must be flawless (or near flawless, for some older models); some light wear to the case is acceptable; all parts must be original to the watch itself, except for the crystal.

So US$ 1800 to 2200 is a little optimistic for this watch in my opinion.
