I have decided to use the clock timing from the PC clock updates. It seems a valid approach as the PC timing just becomes the crystal that the watch used. Otherwise the watch section would be as accurate as the timer in the HP-45.

The Options Menu -> Timing Adjust is still required because the code execution timing is not linked to the PC clock and even though the time will remain accurate you might see the seconds update appear to skip a digit every 20 seconds or so. This will happen if the display refresh is taking slightly longer than 1 second. Just use the adjuster to speed up the simulation a little bit until you see the timing increment normally. The adjust value is stored in the emulator ini file.

The 'a' and 'p' buttons seem to function ok now.

New download available.
