Papers missing for ROO elephant. Value?

[pandaMan]

Hello forum members.

I recently bought a pre-owned ROO elephant as I have posted on this forum earlier this week. I noticed right away that the papers were missing for the watch and had asked the dealer to check if it didn't get sent. Unfortunately they could not find it and believe it got lost somehow.

I trust that the watch is real is since the dealer is very reputable and I don't mind buying the watch without the papers as long as the price is right.

They said they would give me a discount back and a "certified appraisal with the matching serial" as quoted from them.

How much would a preowned ROO elephant in good shape with only the box and manuals go for? I realize that a lot less people would be willing to buy an incomplete set but I'm not really considering this for resale later; I'm more interested in making sure I'm buying for a fair price. What would be the value of the papers?
