Both appeared at the same Geneva auction a few years ago. 3rd - RG or WG 2 button 2523 WT with cloisonné map, whichever is more mint. I love WTs and this is the ultimate for me. 4th - 2499 RG 3rd series, the super mint one coming up next month for auction in Geneva. Why? Why not? 2499 for me is the ultimate reference. And 5th, the unique WG 3448 G red dot. Why? The incredible 3448G "with a twist".
