This is just the watch itself. The wrist size is approximately 18.5 cm. The glass appears cloudy when exposed to sunlight. Buttons like the stopwatch are stiff. They don't activate or reset unless pressed firmly. When the watch is shaken, the band rattles. This is not from the watch body. It worked after replacing the battery, but waterproofing has not been confirmed. This is an old product, so there is no warranty of any kind.
