I think this may be the cheapest annual calendar chrono that I know of. You may be able to negotiate with the ADs rather than going straight to boutiques.

Besides marketing and all I think another factor is that their main selling point is a movement rather than a specific watch model. When you think of Omega you think of the speed and sea masters; when you think of an El Primero, well it comes it too many flavours.
