The watch that tracks your favorite stock

If you follow the financial markets and have penchant for timekeeping, you may be interested to know more about a watch that can monitor shares and currencies. Invented by start-up watchmaker Hoptroff London, the "Stock Market Watch" uses Bluetooth technology to display if a stock has gone up or down (on a scale of +10 to -10) by close of trading. Hoptroff Managing Director Richard Hoptroff explains the product to Bloomberg. (Source: Bloomberg)
