Amazon.com: Casio G-Shock GWN1000B Master of G Series Quality Watch - Black / One Size : Clothing, Shoes & Jewelry
Gulfmaster GWN-1000. My favourite of the Gulfmaster series: More features than the GN, plus solar. Not as many features or upgrades as the Q but I wouldn't need those anyway. I work offshore and this has everything I need. : r/gshock
