In Chinese culture, why is it considered unlucky to give someone a watch as a gift?

In Chinese, the phrase "giving a clock" (sounds like in English - song jong) is extremely close to the Chinese phrase for 'attending a funeral ritual' (song zh?ng). Therefore it is bad luck to give a clock or watch as a gift in China.

Additionally, clocks and watches are a symbol for running out of time which is worrisome for elderly Chinese. Giving a clock or watch as a gift is considered the biggest faux pas in Chinese culture.
