With the Apple Watch release still months away, plenty of details — like the timepiece’s price and battery life — remain unknown. But the release of WatchKit this morning sheds new light on Apple’s most personal product ever.

We dug through the new WatchKit programming guide and Apple Watch human interface guidelines this afternoon and found a few details that weren’t mentioned in the keynote, such as a special new font designed to look good at any size on the Apple Watch’s tiny face.

Here are five new Apple Watch details buried in the WatchKit SDK:

The mad dash to develop the first wave of Apple Watch apps has just begun, and to go along with the new WatchKit for devs, Apple has also released the first iOS 8.2 beta this morning.

iOS 8.2 beta 1 includes support for WatchKit, which allows Apple Watch apps to connect to and run processes on your iPhone in the background. In a press release announcing the update’s availability, Phil Schiller said, “With the iOS 8.2 beta SDK, developers can now start using WatchKit to create breakthrough new apps, Glances and actionable notifications designed for the innovative Apple Watch interface and work with new technologies such as Force Touch, Digital Crown and Taptic Engine.”

Release notes for the beta don’t mention other major new features, but we’ll report on any surprises we find, once we get it installed. The iOS 8.2 beta is available to registered developers in the iOS Dev Center, along with a new Xcode 6.2 beta as well.

As promised, Apple has given third-party developers tools to start making apps for the upcoming Apple Watch. Today the company announced the availability of WatchKit, its new SDK for creating app experiences on the wrist.

With WatchKit, developers will be able to make actionable notifications, Glances “for timely information accessible by an easy, quick look,” and eventually full-fledged apps. Early WatchKit partners like ESPN, Instagram, and American Airlines have already tested the new APIs for future versions of their apps.
