Love Black RL PLM & Super Love the Lumen Moonphase ( I have this one - it's just amazing! I just stare at the dial all day long. It's mesmerizing. Definitely get this one! ).
For me, once you past about $150k - 200k, it is pretty hard to justify a Lange, unless of course money is not an issue. In the $150k - $500k range, you are faced with an array of all time grails to choose from - from Patek 5970, Split Second 5370, or even 3448. Rolex MOD Subs, Pandelone's, and the complicated Independents too. Loads of choose from.........
All the best!
