Apple Watch could disappoint early users: Expert

Apple's stock after Watch launch

The much-anticipated Apple Watch has been officially released, but consumers may want to see a larger screen on the device before sales really take off, according to one expert.

"...You've got to remember, the whole reason this new iPhone has done well is [that it has] a bigger screen. So now we're going to a smaller screen? It doesn't make the most sense," said Patriarch Equity CEO Eric Schiffer in an interview on Friday with CNBC's Tech Bet.

"There are a lot of question marks as to whether this is going to be a long-term seller. It's a wait and see," Schiffer said.

In the short term, however, the official launch is likely to send shares higher, Schiffer said Friday in an email.

And many tech consumers seem interested in the Apple Watch as it is.

About 4 percent of adults in the United States are thinking about buying the watch in the next three months, according to a survey by Prosper Insight and Analytics conducted in April.

That amounts to 10 million consumers considering that purchase in the near term, wrote Prosper's Principal Analyst/Consumer Insights Director Pam Goodfellow on Forbes.
