Sounds like they will be fully stocked for Xmas. Looking at the split of orders, I'm guessing they have sold around 5,000 watches since launch around a year ago.
Judging by the commitment to get these 15000 new watches by november, I would say they are planning to sell as many as they can in that 2 months roughly before Xmas, with JB-hifi stores the major rollout. This will be a good test of word of mouth and the products ability to really jump off shelves.
