I got what amounted to a little under 10% off on a new 3861 Speedmaster moon watch with hesalite from an AD in Orange County CA exactly 4 weeks ago. This was the last one they had in the back inventory, and I preferred to get a "fresh" sample from the back instead of the one in the case that everyone handles. I have never purchased anything from this shop before and I don't exactly look like someone who will be making regular high-end watch or jewelry purchases (I'm not - this Speedo was the first "luxury" watch purchase of my life, and more expensive than anything else I've ever bought that couldn't be driven or lived-in). I went in ready to buy and told them I was ready to buy, and asked if they would be willing to offer a military discount (I'm a retired reservist, so I can't start shopping AAFES until I'm 60). We haggled a little and settled on a number I was happy with, which ultimately worked out to about 9.5% off of the "out the door" price when factoring-in the sales tax.
Having done some research before the purchase, I was considering the 1861. The previous 1861 model is almost $1,000 cheaper retail, and includes an additional NATO strap, a strap-changing tool, and an eye-loupe. So Omega increased the price, decreased the "bonus" items in the box, and apparently pressed the ADs to reduce discounts.
Regardless, I'm still confident I made the right decision going with the 3861. Maybe I could have gotten it for a little less if I looked around some more or went up to LA, but there's value to my time too, and I don't have any established customer relationships with any place anyway. I have no regrets and am happily wearing my new moon watch almost every waking moment.
