My LPL timer is just as simple.  It has two dials, one going 10, 20, 30.../
0.2, 0.4, 0.6, 0.8, and the other going 1, 2, 3...10.  You set the two dials
to represent the time.  There is also a switch that multiplies the number by
10.  Then, there is a toggle switch "focus/time" and a push button that
starts the timer.

I don't know who markets it in the U.S., but probaby Saunders which imports
LPL enlargers.
