Good question: 1. 5131R; 2. 5131/1P; 3. 5131G; and 4. 5131J. I do like the 5131/1P, but ultimately the bracelet is quite prominent given its fully polished style. That might have the 5131R pip it to the post for me. But it is a very close call!
all four of them ! Each has a special meaning to me. G & P were produced by Anita Porchet and her team. R has the most meaningful map to me, whereas J was my first love when it came out.
