What's the Omega AD Average discount for Speedmaster Moonphase?

[Rolexlover123]

Hi all, I'm interested in getting a new Omega Speedmaster Chronometer Moonphase Chronograph 44.25mm, stainless steel with Blue ceramic dial, Blue leather strap.
Reference # 304.33.44.52.03.001

What is the typical discount you would expect from a AD for this piece? The lowest Gray prices I have seen is at AuthenticWatches.com & jomashop at ~$6.9K. Alan Furman, another grey dealer with a physical store (unlike the other two online greys) sells it for $7.8K. I'm curious what is the premium ADs sell it for after factoring in a discount. I went into an Omega Boutique and the Sales Manager quoted me only 10% discount. I thought that was not a great deal considering Rolex offers 10% to 15% at ADs on some of their watches and Rolex is the current hot item right now. So, am I right to feel that 10% was too low and should I expect something around 20% to 25% discount from an AD since online greys are selling at 36% discount?
