simple IFR timers

Anyone know of a source of a simple timer for approaches? I had one
years ago that was very simple. It was round with two buttons, one to
start and stop the timer and another to reset it. All I can find now
are the West Bend and others that have a lot more features than I need.
Unfortunately, the yoke timer in the airplane is toast so I'm looking
for something I can just velcro to the yoke or panel.
