Help with a new strap
Hello,
I just bought this amazing Lange 1 1A (référence xxx). First Lange 1 limited edition, first guilloché dial, first yellow gold dial and parts of the mouvement. Unfortunately it came with a basic plastic strap from the auction house as they can’t sell/export proper alligator ones. My nice SA from the boutique has offered my to choose anyone from Rousseau but having never change a bracelet in my young collection I have no idea what to to for…
So any help/suggestions appreciated.
Thank you!
