I've found Decathlon stuff to be very reliable. Didn't hesitate when I saw this watch - cheaper and nicer than any alternatives on the market.
We bought this watch for our six year old daughter, and she loves it. The rubber strap is comfortable and the colour is lovely, but most importantly is has helped her so much with learning to tell the time. The face numbers are clear and easy to read, and the minute numbers on the bezel, which does not move, help make sense of the five minute increments. It is also living up to being waterproof. Putting the strap on at first was tricky, but she has got the hang of it now. It was not too expensive so good value for money.
Comfortable, great colour, easy to learn time.
