You have an infinite loop. The pause() call permits the infinite loop to be interrupted by a GUI callback, but the code in the infinite loop will not continue running until the callback returns. Using pause(1) does not mean that 1 second later, no matter what MATLAB is doing, that control should be given back to your infinite loop.
What you should do is create a timer object that should run evern 1 second. The code for that timer object should update the GUI clock, and then should return.
I think you will find code for a clock in the File Exchange.
