Not sure who "we" is, but any replaced parts affect value regardless of make or model.
Here is my .02-
Since you have not provided any details on this watch, can you tell us how you know these were replaced by Rolex?
For me, a watch like this draws serious red flags. Generally when you see a watch with replacement hands, dial and bezel...not to mention a case back that has little or no markings...it is a clue. The first question you have to ask is why?
Why was so much replaced? If the seller is not providing a service receipt from Rolex, then you should assume Rolex did not do the work. With wholesale replacement of parts its generally an indication that this watch had a rough life or something worse happened. Why take the risk? Its not like you can't find 10 more honest examples for sale any day of the week.
If you really believe that all these replaced parts don't affect the value, then you are kidding yourself. The value of this watch is considerably lower than an honest example. If the watch is priced accordingly, and you like the way it looks then buy it. But don't fool yourself into believing that this watch is worth as much as an honest example, or more importantly that it will be easy to sell if you ever decide to do that. It will be far harder to sell this watch later...so as long as you understand that or don't care about selling it later then do buy it because you like it.
Ive been collecting for 30 years, and Ive seen a lot in that time. From my experience, a watch like this is a gamble..an unnecessary gamble since honest example are easy to find. YMMV
Honestly if you want more advise, then you must provide more information. The selling price is relevant here, as is the sellers description...why not give us facts? Without more information, there is little more we can tell you.
Impossible to tell from a few photos, but I would question that bezel.
