This Stopwatch icon has Android KitKat style. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
A stopwatch is something that ticks and is handheld. It is circular with a little timer in the right so that you can click it and start + stop time. It has hands that keep track of how many seconds it has been.
