Is the Apple Watch the Next Huge, Medium, or Mini Hit?

The Apple Watch isn’t going on sale until next year, but already everyone from Wall Street analysts to luxury fashion executives is trying to handicap future sales of the groundbreaking device.

Among the finance set, estimates range from a few million to almost 40 million in the first year of sales. “The detail that went into the design, including the watch bands, is impressive and not fully appreciated yet,” UBS analyst Steven Milunovich wrote in his assessment of the watch. He sees 24 million sold in the first year and 40 million in the next year.

One of the most optimistic analysts, Brian White of Cantor Fitzgerald, expects Apple will sell 37 million watches in the first year, outpacing the 20 million iPads sold in the tablet’s first 12 months. “We believe Apple Watch will prove to be a home run with the fastest, new product, first-year unit sales volume in the company’s history,” Fitzgerald said last month on CNBC.
