It measures dives up to an improbable 24 hours

It measures dives up to an improbable 24 hours, and su***ce intervals up to 48 hours. Logs of the last ten dives are kept in memory for displaying.On the top portion of the screen, you have a 7-segment tide graph, moon phase, and circular timer display. DLC is perfect for salt water, so I'd say that this is a very good value for the money.Today's review is Casio's latest in their Frogman line of G-Shock dive watches. These are the first in that line to have atomic timekeeping and solar power. Let's take a look and see what you get for a list price of $725!Specifications:Water resistant to 200m (660ft).Dedicated dive timer with su***ce interval measurement and logbook.Tide graph and moon phase (based on UTC offset and lunitidal interval).DLC-coated stainless steel case, integral rubber strap with double-tang buckle.World time in 48 cities (31 time zones).Automatic and manual EL backlight.Six-band radio reception (Japan, US, China, UK, Germany).Machined aluminum bezel with stainless steel screws on the face.24 hour countdown timer.Five alarms.26 month power reserve with H/M/L display of charge.58.3mm by 53mm by 18mm, 115g.Please read on for the full review and pictures. One major win from the size increase is the more legible display, which I do appreciate.The new Frogman increased quite a bit in cost over its predecessor. From reading the press releases, I think that most of that is due to materials. Dive watches have issues with corrosion, and the G-Shock line has plastic on top of metal which traps moisture next to steel. Even stainless will rust in those conditions, so the new Frogman goes to DLC-coated stainless for the case and and a cool DLC-coated bezel with steel buttons and DLC-coated crown. Expensive, yes, but probably worth it in the dive world.
