Granted that it may not be easy to do being an ultra thin and all. But its info that you don't need to be reminded of every day. Plus, I don't even mind having a sealed case back with just an small window showing the year perhaps.
Having said that, if I were in the market for a perp, this would be on my number one list. It is very beautiful and prefer it over the silver dial version.
Thanks for showing pics of it from time to time 
Best, Echi
