BEIJING, March 10 -- Apple Inc. unveiled its first wearable product at its launch event at San Francisco on Monday. The product, known as Apple Watch, will go on sale on April 24 in eight countries, including China, the only developing country on the list.

Apple Inc. has done more to draw the attention of Chinese customers on the event.

A video at the beginning showed the footage of an Apple Store's opening ceremony at the West Lake in Hangzhou, a city in the eastern province of Zhejiang.

WeChat, a popular Chinese messaging app, is among one of the built-in apps on Apple Watch. Users can click on the watch to reply to WeChat messages with texts or emojis. Some cute emojis even appeared on the screen.

Weibo, China's counterpart to Twitter, and Alipay, Alibaba's online payment system, weren't left out either.

Apple Watch's price starts at $349, and could go beyond $10,000 for a solid 18-karat gold version.

Chinese element is also weaved in when the screen shows the cooperation partners with ResearchKit, an initiative for public health. Xuanwu Hospital Capital Medical University in Beijing stands with Stanford Medicine, University of Oxford and some other hospitals and university medical centers.

ResearchKit provides a platform for apps to collect data on health and disease with participants' iPhones.

Back in October 2014, Apple's chief executive Tim Cook had also repeatedly talked about Chinese elements on its event. He showed an edition of fashion magazine Vogue China, with the cover demonstrating Chinese model Liu Wen wearing an Apple Watch.
