If you’re looking for a value proposition, a diamond dial is almost never going to be it. They are harder to sell with an inherently limited market. I would consider this to be overpriced unless you are specifically fixated on the Tahitian Mother of Pearl dial. This is a 36mm precious generation DJ with the 3135 movement which while solid has been around since the 80s.
I kinda disagree though if I’m selling a watch (and I have sold a Rolex before) I don’t have the tools, clean area or desire to risk anything compromising the water seal. If it’s a private seller with good feedback I guess I kind of see where they’re coming from. I’ve never been asked to do it fwiw you’d be entitled to a PayPal dispute or chargeback if it’s fake so you can evaluate for yourself, anyone can fake pictures tbh
My rules are simple - you must be able to afford it in cash and you’re getting the best possible price available on something that has historically had low depreciation
