Think I'll stick to my Oris Artellier Complication - it has a Moon dial so I always know when full Moon is.

It has come in useful the last two months when there was so much cloud cover that the Moon didn't show at all

It also tells me the day of the week, the date, and also a second time zone. It hasn't been into space, but I did point it at Orion the other night - does that count??? And it didn't cost $28,000
