I'm at Sunflower hotel. I would like to know a good place to buy watches, clothes cheap and quality.

Are you stay at Wuhan? Well, if so, I suggest you go to Hanzheng Street to get the above things you mentioned. You can find many clothes wholesale stores there, extending to the nearby Jijiazui, Duofu Road and Daxing Road.
The MTR station you mentioned is not into use yet. Anyway, here is the direction to the Hanzheng Street:
you can walk from the hotel to Wuluo Road, Fujiapo Bus Station to take bus no. 590 or 703 and get off at Yingwu Dadao Guqintai Station. Upon your getting off, you can walk about 700-800m to Hanzheng Street.
Nice day!
