For a stupid mistake, I purchased an incorrect watch model. After 2 hours I replied to the order confirmation email to explain that there had been an error and that I wanted to change it immediately, sending the model name and link. after TWO DAYS, as if nothing had happened, they answered: "thank you for your order, we have just sent your (original) order, if you want, you can also buy the other one by making a new order" !!! Thank goodness this was my fifth purchase! “Wonderful” customer care. What's more, the watch takes over 20 seconds a day.
