SAN FRANCISCO: Apple is expected to spotlight its smartwatch, iPad, and subscription services on Tuesday as it strives to reignite growth with a must-have holiday line-up.

A keenly anticipated iPhone 5G considered vital to the company's fortunes will likely star in a separate event later in the year due to disruption in production caused by the pandemic, according to analysts interviewed by AFP.

Apple shares that had been soaring have slipped by more than seven percent this week.

The Silicon Valley-based iPhone maker on Friday had a market value of $1.92 trillion based on share price, down from a record high of $2.3 trillion at the start of this month.

But Apple remains the most expensive company on Wall Street. Amazon comes in second with a market value of $1.56 trillion dollars and Microsoft is third with a value of $1.54 trillion dollars.

The Apple event was teased with a cryptic invitation reading "Time Flies." The company has remained mum about what it has in store.

It is expected to showcase products or services other than iPhones being launched for the year-end shopping season.

That opens the potential for updates of Apple Watch, iPad, MacBook computers, services, and even Apple TV set-top boxes, according to analysts.

A new iPad model could include enhanced augmented reality capabilities, and Apple services such as music, news, and television might be offered in an attractively priced subscription bundle, analysts said.

The latest software powering Apple Watch already indicates sleep tracking is coming, and the company may enhance features for fitness or health uses.
