Thank you very much for your response. It was very helpful. The watch is a pristine 1954 2525 with the dart indices. Looks like the watch was kept in a vacuum for the last 56 years. This is my first PP. Simple elegance...thanks again.
I would like to replace the non PP buckle that is on the watch with an appropriate 50's vintage tang 18k YG. Alligator band is also non PP but is beautiful and is 18/16mm. Any suggestions would be appreciated.
