The safes will likely be used to carry both to-be-sold inventory as well as to store demo units from the show floor overnight. The custom-designed safes will be outfitted with Apple Watch MagSafe chargers in order to keep the demo units charged up and ready to go for the next day of business.
Apple has said in the past that the Apple Watch Sport will have a starting price of $349, but it has yet to comment on the cost of the gold and rose gold Edition collections. Rumors have ranged from over $1000 to up to $10,000. Given the small size and high value, like jewelry, some form of security certainly makes sense.
The Apple Watch ships this April.
