Since the launch of Apple Watch smartwatch in April, the American multinational technology company  has sold more than two million units. Initially, Apple was able to sell around 200,000 units every day from the date of the product's release, but now things are not going well for the device.

Based on the data gathered by Palo Alto, California-based Slice Intelligence, MarketWatch shared that Apple Watch sales have plummeted by 90%, selling less than 20,000 units daily in the U.S.

It also appears that people were more likely to buy the cheaper watch model from Apple, the Apple Watch Sport. The survey report said two-thirds of all Apple Watch units sold up to this day are the Watch Sport, with a starting price of $349, compared with Apple Watch, with a starting price of $549.

As for its18-karat gold model, called the Apple Watch Edition, launched in an attempt to cater to the luxury market, the report found that only less than 2,000 units have been sold in the U.S, which is considered not so impressive.

Still, the gold watch, priced at a minimum $10,000 per unit, has helped Apple earn several millions in revenue.

The numbers generated by Slice is based on electronic receipts sent out to millions of customer email addresses after purchases are made.

Smartwatches have been around for quite some time, long before the launch of Apple Watch, and those earlier models weren't that much of a success in the first place, according to a report from Digital Trends.

This could be the reason why analysts predict a decline in sales for the new watch. Generally, smartwatches do not have that much of an impact, unlike smartphones.

There are still several months left before the year ends, and Apple still has to see just how many Apple Watch units will be sold by then.

Meanwhile, MarketWatch reported that Wall Street has been trying to figure out the sales status of the watch, but Apple refused to give concrete numbers. The company has yet to respond to requests for comment.
