Thank you so much, dear Gordon,
for sharing the very interesting article full of information.
Of course, having Anita Porchet's signature is a major bonus and almost a "must-have".
Concerining the 5531, I happen to like the maps more than the landscapes: my personal favorite would be the Geneva map, ref. 5531R-015 with the "hidden" AP signature.
But my favorite world time references with enamel painting would be a 605, a 1415 or a 2523.
605
1415
2523
Best, Emmanuel
