It may take about 5 days. As mentioned in previous reviews, wash. They started to fade after 2-3 days. Wouldn't recommend it. My sons just wanted "galaxies". Even though the reviews said they rubbed off, they wanted to give it a try. This is a vivofit jr 2. The straps are quite elastic so you should be careful not to tighten/extend them too much to avoid losing part of the watch.
