Possession of this clock for several months and it runs precisely and without problems. The silicone band has me pleasantly surprised, because it is very flexible and resistant. You must have it not too tighten, as it is not permeable to air and you start to sweat easily. But for the cleaning is simple with water. Otherwise, the clock adjusts for any occasion. She looks real even-quality than in the pictures and at the same time it is very suitable for sports activities. I would have still wished pointers that are visible at night but the date display is more important to me and therefore I am completely satisfied for that price.
