Hi all, newbie here! I've decided to purchase my first G-shock watch as a sort of weekend/tool watch for swimming and recreational diving. I'm stuck however between the mudman and the gulfman and i need help deciding. I'm quite taken by the mudman's ruggedness, but at the same time i like the idea of the titanium in the gulf. I have a few stainless steel watches now so titanium would be something new. I have noticed that the mudman is quite popular among the members here and i'd like to know why exactly is that? Also does anyone know whether the gulfman's pushers can be used underwater? Lastly i have a question regarding those nubs on the mudman's caseback. I've read some saying it makes the watch uncomfortable, i've tried the watch on myself at an AD, and haven't found it to be bothersome. But i'd appreciate comments on this. Sorry if this post seems so long! TIA guys.
