Depending on whom you ask, smartwatch sales are fighting, or they’re red-hot. Apple falls into the latter camp, according to CEO Tim Cook, who says that the company simply broke a record with Apple Watch sales.

“Sales growth is off the charts, ” Cook told Reuters in an email message. “In fact, during the course of its first week of holiday shopping, our sell-through of Apple Watch was greater than any week in the product’s history. And as we expected, we’re on track for the best quarter ever for Apple Watch.”

Cook’s rosy picture seems to fly in the face of a report simply issued by research firm IDC, which says that Apple Watch shipments declined by 70 percent year-over-year during the third quarter. Cook’s remarks to Reuters were in response to a query about the IDC report.

IDC claims that it’s considering a big switching in the overall wearables marketplace, with more straightforward, single-purpose fitness trackers from Fitbit and others now making up a whopping 85 percent of the market.
