Precision to a hundredth of a second

[mombasa]

I made a stop watch with a PIC18F252 using the Timer1 driven by a DS32khz instead of the usual quartz that allows me a very good precision. So far I have been content to have an interrupt every second but now I want an interrupt every hundredth of a second to render more precise timing. In your opinion, how should I handle the Timer1 for it? Thanks & Regards
