Comments about Casio Casio G9100-1V G-Shock Gulfman:
I use this watch regularly for diving. Tracking tides in Narragansett Bay is a very useful feature, and its display conveys a lot of information at a glance: time of day, date, tide and moon phase. Very accurate and rugged. Its bezel adds bulk but protects the crystal face, and a titanium back keeps the watch lightweight but pressure resistant. Good design and an excellent buy!
