There's been quite a bit of pessimism surrounding Apple (NASDAQ:AAPL) Watch sales during the past few months. Much of it is due to third-party estimates on how the smartwatch market is faring, and market researcher IDC has some pretty gloomy figures for both the smartwatch market as well as Apple Watch specifically.

IDC put out estimates for the smartwatch market at the end of October, followed by numbers for the broader wearables market just yesterday. In both instances, the researcher pegged Apple Watch unit volumes at 1.1 million, down 72% from a year ago. Apple Watch has been on sale for six quarters, and for reference, here are IDC's estimates for the past year and a half.

CEO Tim Cook recently responded to an email question from Reuters, and provided some rare commentary. "Our data shows that Apple Watch is doing great and looks to be one of the most popular holiday gifts this year," Cook told Reuters.  He continued:

Sales growth is off the charts. In fact, during the 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 is clearly on the defensive and wants to reassure investors that Apple Watch sales are doing just fine. Unfortunately, this attempt falls flat.

There's no context

Making vague statements about Apple Watch performance is meaningless lacking context. "Off the charts" is a close cousin of "doubling down," another somewhat abstract phrase that business leaders like to use without having to actually provide details. On top of that, the product's history is so short that it shouldn't take a lot to post the best week ever. The most meaningful information that Cook shared is that Apple is trending toward the "best quarter ever," which is still frustratingly vague even if it's a little more relevant in terms of financial reporting.

Additionally, Cook is referring to sell-through, while IDC measures unit volumes based on channel sell-in. Sell-through is what really matters if you're trying to gauge customer demand.

While it's not reasonable to expect Cook to disclose granular detail in this medium (which would likely be a violation of Regulation FD anyway), the broader point is that Apple is fully capable of providing as much context as it wants around Apple Watch sales. It's just that Apple wants to provide as little as possible. This is the type of financial obfuscation that has been doing for years, much to the frustration of its own investors. Cook's comments are comparable to this imagined conversation with Jeff Bezos. Growth off an unknown base doesn't impress anyone.

Here's a little context

There is still some context worth considering, though, but it has nothing to do with Cook's email. Apple launched Apple Watch Series 2 at the very end of Q3 and only in limited quantities. The original model had a roughly 18-month product cycle, which is longer than iPhones but shorter than iPads and Macs. With the reduced price of Series 1, combined with an improved Series 2 with new features and functionalities, I would certainly hope that Apple Watch jumps to new highs this holiday shopping season. In fact, I'd be surprised and disappointed if it didn't. Cook is essentially just reaffirming something that investors should have been expecting anyway.
