Thus most people would say keep the Lange. I would agree with Padj, just check which you use more and sell the one you wear least.
Good luck on your hunt for a Lange 1. I almost pulled the trigger on a white gold/ blue hands before but hesitated.
I then saw a watch I was eyeing for (PP5960) and pulled the trigger, so now the Lange 1 is again on hold.
I am still waiting for the new Lange 1 with day/night indicator moonphase.
