I'm looking for a G-Shock that I can use for timing the play clock in high school football games. I typically countdown from 20 seconds and then hand signal the last 5 seconds. I was almost ready to pull the trigger on a 7900, but read in the manual that the lowest value the countdown timer can be set is one minute. I need to set the timer to begin countdown at 20 seconds.
Anyone know of a G-Shock (similar to the 7900) that has this feature?
Thanks for any help.
