I agree that a clock should absolutely open faster than a browser, but it would be good to know what this metric actually represents. I don't know much about this style of universal binaries, so I don't know if the binary being "true 5-arch universal binaries" is the focus of the application start time metric.

Support for different architectures doesn't impact start time much. The code for the different archs is in different chunks of the file.

Linking more libraries slows down launch due to initialization that happens to get the libraries ready to use. Besides that it's mostly what the app itself is doing on startup.

So yes, beating Safari for a tiny app is… a good thing, but not very impressive.
