Try Australia Watch and Jewelery at 39 Miradoe Mansion G/F,54-64, Nathan Road in Kowloon.
The owner, Steven Lee, gives a good discount to airline crews on watches.
Also Florie Yu at PanAm Pearls behind the Hyatt for pearls and chinese goods.
For tailor goods, Winston Co at 5-6 Middle road, 1/floor right behind the Sheraton in Kowloon.
All good UA shopping places.
Have fun!
