The clip, first shared by 9to5Mac, was recorded inside an Apple Store by an enthusiast and should be taken with a grain of salt because it shows an in-store unit which runs demo software that may or may not be exactly the same as the actual shipping Watch OS.

A report back in January claimed the S1 processor inside the Apple Watch would bring A5-like performance to the device, helping refresh its display at a silky smooth sixty frames per second. Of course, we won’t know for sure until first Watches land in customers’ hands this Friday, at which point we expect iFixit’s repair experts to perform their ritual teardown dance.
It’s a bit strange that booting the Watch would take longer than starting up the iPhone 4s, which also runs the A5 chip. The difference in boot times between A5-driven iPhones and Apple’s wearable gizmo might indicate that the S1 inside the Watch is running at a lower clock frequency to help extend the battery life.
