Similar to the Chinese government, which considers dissemination of seemingly innocuous data as capital crimes, Apple also strives to keep a tight lid on its new product statistics to help control its stock price and manage investor expectations.

So recent data published by a Chinese third-party mobile data service platform called TalkingData claims to have thrown the doors open on what Apple is doing in China. TalkingData claims that Apple sold over 1.07 million Apple Watch products in China.

The Apple Watch was launched in April 2015 and is currently available in 19 countries. Apple has not revealed the detailed sales volume of this smart watch product; however, Apple's CEO Tim Cook said in July that its sales have exceeded the expectations of the company.

Statistics provided by the market research firm IDC showed that during the second quarter of 2015, Apple Watch shipments reached 3.6 million units.

Steven Milunovich, an analyst from UBS, also said that Apple Watch saw the largest sales in U.S., Canada, U.K., and Hong Kong. Comparatively speaking, the Chinese mainland market is hard to predict, but the sales in Hong Kong can be taken as a reference.

Cook also revealed in a previous interview that Apple's Chinese businesses continued to grow at a high rate and were not affected by depreciation of the Renminbi.
