It depends on what is the purpose of giving the corporate gifts.
If you are planning to host an exhibition, you will like to give away gifts that maximise your advertising value. Corporate Gifts like low cost pens, button badges, tissue papers printed with your corporate message makes a great gifts. I personally like to give out stickee pads, with well designed layout. Each pad comes with 50 sheets full of your company message. This gets circulated to 50 other people when it is used to pass messages, as it intended to be.
On the other hand, if you going to give a staff for serving 20 years in the company, an appropriate gift that shows how much you oand treasure his services and contributions should be given. Perhaps Wenger watch will be greatly treasured.
