The invite asked us to "Spring forward," confirming that this one's almost all about Apple's first smartwatch and giving us a helpful reminder of the US daylight savings time change.
Sure, we got hands on time with the Apple Watch at the iPhone 6 and iPhone 6 Plus launch event in September, but there were several key details missing about the "iWatch."
We're also anticipating a few more surprises from Cupertino, including an all-new MacBook and an update to iOS 8.2.
Release date
We kind of sort of know the Apple Watch release date. It's coming next month with an official April launch window, but we should know today.
Apple loves launching new iPhones and iPads on Fridays, so its smartwatch may be due in stores on one of four days: April 3, April 10, April 17 or April 24 if the pattern holds.
Price
Think Android Wear watches are expensive? Apple Watch's price is set to be even higher at $350 (likely north of £220, AU$400).
And that's just the start. Apple Watch Sport is expected to be the cheapest edition with a lightweight aluminum casing, Ion-X glass and rubber-like fluoroelastomer band.
The regular Apple Watch, which will hopefully get a better name, upgrades to a stainless steel casing, sapphire glass and metal band options. That comes at a cost.
Reports indicate that the premium Apple Watch Watch Edition will cost as much as $10,000 and be kept in a safe because of its 18-karat gold value. We'll know for sure soon.
Apple Watch: what else?
Well hopefully we'll get more of an insight into the battery life of the Watch, as conflicting reports continue to muddy the waters.
In one camp we have Tim Cook saying the Apple Watch will last a whole day on a single charge, but there are rumors suggesting with heavy usage it may be done after just 2.5 hours.
Apple's likely to showcase a whole host of Apple Watch apps from third party developers, allowing the Cupertino firm to really show off what its wearable can do and thus hopefully justifying the high price tag.
There will be a strong health and fitness vibe running through the Watch's marketing and release notes for the upcoming iOS 8.2 operating system may see the mobile software launched alongside the Watch.
One more thing
As well as getting more details on Apple Watch we're also preparing ourselves for one of Apple's famous "One More Thing" announcements.
While nothing is set in stone there are a number of devices which could also sneak out today, including a 12-inch MacBook, Retina MacBook Air or even the iPad Pro.
