Best to inquire in store if you can. I'm roughly 13.3 cm and still have little room in clash 14. Depends on shape of your wrist too...Have fun shopping!May I ask what is your wrist measurements? My wrist is 13cm on a good day and it could go down to 12.5cm. I'm wondering if clash 14 will be too big and whether Cartier will do custom size that small. Thank you
