Skip the fake Rolex. It is not worth any price.
Weather is expected to be bright and sunny for the next several days, so plan outdoor activities.
As mentioned by members here, take a tram up to the Peak. Better yet, try to time your arrival to the Peak at around 6pm to see the magnificent sunset. Afterwards, you can have a relaxing dinner at Cafe Deco at the Peak Galleria.

If you can tolerate the humid weather, ask the waiter for a table outside to enjoy the meal accompanied by the night skyline. There is a Madame Tussauds Wax Museum at the Galleria should you be interested in such exhibition.
To escape the concrete jungle and the overwhelming crowd in the city, my next recommendation for you is to take a public bus #6 or 6X from the bus terminus underneath Exchange Square and head to Stanley Market/Beach. You get off at the last stop. If you are not prone to car-sick, sit in the upper level of the bus and try to find seats at the front. You will then be able enjoy the view along the exciting and sometimes scary ride.
Stanley Market is a bazaar that, honestly, is a tourist trap. Souvenir prices are inflated, but, it is a good place to try your bargaining skills. Once you escape the bazaar unharmed, there is a boardwalk with numerous restaurants and bars for your enjoyment.
