Surprises me too but trying to be objective and stand back and look at things, there are a number of things that may be a partial reason.
There is no doubt Rick Marei has been behind some darned good watches with DOXA, Aquastar, Synchron and Aquadive. Pretty much any limited edition he has put out in the sub $1000 range has sold out in days. Times have changed and money is tight for most people. It's easier to justify 990 bucks, not so easy with 2,800.
The size may put some people off, but I really am being honest when I say that the watch wears incredibly well even on my somewhat less than Popeye proportions 6.75 inch wrist. The changes to the case and use of the vintage style 18 star caseback and the 22mm lugs make it far better wearing than the vintage 500 or H1, even though it is heavier when wearing it on a bracelet.
The watch world has definitely moved in the smaller, lighter and thinner direction. I've beaten the drum about flat casebacks for years and even DOXA have finally started to get with the program
Not everyone wants the complication of the chrono function and are happy with the Benthos look and feel of the H1 at almost 1/3 of the price. And of course, there are alternatives out there that will vie for the money.
I don't doubt it will sell out and as soon as people start to get their watches, I think more people will start to see what a cool watch it is. As I said in the review, I believe the new 500 will be another of those...man, I wish I had bought one of those... watches.
Diving Duck, thinks it is pretty slick
