Watch new Apple sold an average of $ 529, including accessories, at the high end of Wall Street estimates, according to findings from research firm Wristly.

Investors are intensely monitoring the performance of Apple's latest invention to see if you can open a new source of growth for a company depends largely on sales of its iPhone.

But the profitability of the watch has been difficult to measure because the prices range from $ 350 for sports models to $ 17,000 for designs of solid gold.

The figures provided to Reuters by Wristly, which surveyed more than 2,200 Apple Watch owners, sit on top of the estimates of analysts, many of whom have pegged the average selling price of the gadget between $ 425 and $ 550.

Apple has not broken out sales figures, fueling concerns among some on Wall Street. The Wristly survey suggests that some investors may have underestimated the profitability of the watch, said the founder of Bernard Desarnauts.

A spokesman for Apple declined to comment on the survey.

Since its launch in March, shortly before the clock hit stores Apple, Wristly invited the people who buy the gadget to participate in a periodic survey about their experiences.

The average selling price is calculated by combining the results of the survey on the model, size and number of bands participating purchased.
