I am familiar with most of the G-Shocks that have the time, World Time, countdown timer and stop watch. I own a GW-M850 and do not like or need the rally timer and another record timer which I can;t even figure out why you'd need one unless you were a high school coach timing track athletes, and if that were the case you'd have a dedicated stopwatch. My Mudman GW9010 has the Rally timer and 2 extra timers related to it, BESIDES the normal countdown timer and stopwatch I am familiar with. Are there Mudmans without all the EXTRA timers? I hate having to scroll past them to get to the countdown timer which is something I always use and usually have it set to 5 minutes.
