Here's an amateurish picture of my very first Ball (and definitely not my last), the Skylab Limited Edition. Numbered and limited to 1600. What I like most about it are:
1. It's a 43mm which suits me very well. It took me quite a while to choose between a 42mm and a 45mm Planet Ocean wishing they had something in between. The Skylab answers that.
2. The bracelet is very, very sturdy plus it is not prone to scratches.
3. I like the semi-domed crystal as compared to the other flat Ball models.
