I only have two, a G series DJ and an M series EXPII and must say I'm relatively content. I'm not a flipper and will never let go of these. I do like to look. Probably will never happen but I do think of adding:
1. GMT Pepsi (but will be first in line and
WILL BUY if Rolex introduces a ceramic Pepsi)
2. DJ II (but fear that then I would never wear my DJ again)
3. Sub C (just because I like the look)
4. DJ on leather
5. DDII
