How do you measure the success—or failure—of the Apple Watch?

That was one of the questions posed early on Thursday at Glance, a day-long conference in San Francisco devoted to Apple’s (AAPL) first wearable device.

Some benchmarks from my morning notes:

80% — Apple’s current share of the smartwatch market
21 million —Projected first year sales (estimate by Asymco’s Horace Dediu)
100 million —Projected sales by 2017 (estimate by Creative Strategies’ Ben Bajarin)
30% —Percentage of Apple Watch buyers who weren’t previously wearing anything on their wrist
6.9 seconds —Average Apple Watch interaction (versus 38 seconds on the iPhone)
85% —Percentage of Apple Watch owners who say the device has contributed to their health
27% —Percentage of Apple Watch owners who say they’ve lost weight
82% —Percentage of early adopters who say they have given an Apple Watch as a gift
46% —Percentage of Apple Watch owners who have used their nose as an input device
