As we reported earlier today, the super-expensive 18kt gold Edition version of the Apple Watch will be very constrained on launch, with the online store showing that shipments are already -- hours before pre-orders even begin -- pushed back until next month, with no specific window for those ordering online beyond "May." Buyers in stores will have similar issues actually going home with one, as only a total of 53 Apple Stores worldwide will be selling the high-end model, at least for now.
