Thanks for your input! But I really do want the big date funtion! Nonetheless, the SunMoon is a stunning watch as well.
A couple of hours ago I visited an AD. Unfortunately, the GMT was only available in RG. Still I realized that the face of the GMT is beautiful, too. I didn't like the black face side, though - I would never wear this side up. And I don't do a lot of travelling, either. So i guess I'll go for the Big Date and save the difference for my next JLC or ML.
