Advice needed on safe selling of Milgauss 1019

[Scribbler]

Hi everyone,

I posted this Q before but it didn't appear (I think it's because I've just joined) so apologies to all if you have, in fact, already seen this.

I have a Milgauss 1019, in excellent condition with the box and all the papers etc, and I am researching the best way to sell it.

There seems to be a huge range in valuations from what I've seen, although I understand that this is a fairly rare/sought after watch.

So what's the best way of getting it valued and sold, would you say?

One of the big auction houses? A Rolex dealer? On this forum? Take a punt on eBay?

Also, what steps could a buyer reasonably be expected to take to satisfy himself that the article is genuine?

And is there a risk that I do the deal then, a month later, the buyer (having sneakily swapped the innards for fake stuff) demands a refund, leaving me with what is now a fake Rolex. Is escrow a normal practice with high value Rolex sales?

As an experienced Rolex-enthusiast, what would you do in my position?

Many thanks in advance,

S
