Yesterday I wrote about how much people love their Apple Watches. Now we have another bit of data (albeit another that needs to be taken with a grain of salt) about the Apple Watch, and this time it’s all about sales. Because no matter how good a product is or how useful it is to the people who use it, it will be deemed a failure if it doesn’t sell “well”. This is especially true of an Apple product, as everything Apple makes is inevitably compared to the iPhone, aka The Most Successful Product of All Time (not its official title, but it might as well be).

These aren’t official sales numbers, but they’re likely a very good estimation from Canalys: nearly 7 million. Early reports pegged first weekend Apple Watch sales at just under 1 million units. If you take Tim Cook at his word that the Apple Watch continues to rise in sales every quarter since launch, then that 7 million number could very well be in the ballpark of the official numbers. That’s pretty stellar and Apple should be very proud. Even if we assume an average selling price of $500 (which I suspect is a little conservative), the Apple Watch is a $3.5 billion business in its first 6 months. Not bad.

That same Canalys study wasn’t just about the Apple Watch, and also looked at other smart watches and fitness bands. They pegged the next closest smart watch company at 300,000 sales over the same period, and the Pebble at over 200,000. Fitbit continues to rise and Xiaomi’s Mi Band just hit 10 million total sales (since its June 2014 release).

I will be very curious to see when Apple finally decides they want to talk about exact Apple Watch sales, but these estimates will have to do for now. I know that I love mine and that’s all that really matters, but it does make me happy to know that tons of these are being sold, if only to know that Apple isn’t going to scrap their future plans for this watch I love.
