First post to the forum - I am interested in purchasing a G-shock for scuba diving. The Frogman is the obvious choice, but I think the Mudman would do as well (and the prices for the used watches are cheaper). One important question I have about both watches is whether the functions/pushers are safe to operate underwater. I specifically would want to use the timer and the light functions. Would appreciate any thoughts the forum may have about the functions/pushers, and about which to purchase. Thank you!
