G-Shock

What is everyone's opinion on G-Shocks for recreational diving? I want a water resistant watch for for OW cert and am saving for other gear including a dive computer. Any favorite models or pet peeves?

Thanks

This is my favorite Casio Diver Watch, the DW-260. Heavy duty, shock resistant case with a 200m depth rating and it's not fat/bulky like the G series.

I have an over 10 year old Casio model DW-6900 G-Shock that I replaced the battery 2 years ago.
When I did I cleaned the o-ring and the groove it sits in and lubricated the o-ring with silicone grease. Torque the backplate cover screws evenly an listen to the watches alarm piezo.If the sound gets to faint you are over torquing the screws.
The watch still works perfectly for diving. What other brand watch could you or would you attempt this with? G-Shocks are a great, cost effective, dive timer.

I love my G-shock.

There are a few threads on here about water resistant wristwatches for recreational diving. The rule of thumb is:

• 200m ratings are typically good to 100+ft depths
• 100m ratings are hit and miss, some will last for years, others will flood, especially if you bump them a bit underwater or press the buttons
• 50m ratings will more often than not fail at recreational depths, especially if you press the buttons

Much of the reason for the discrepancy between WR rating and real-life is because these watches are tested in a static pressure pot, which is very different than in real use where they can be jostled or buttons pressed.

The G-Shocks seem to be great, reliable watches for diving. I use a Timex Ironman 200m, which is another recommended brand/model. This one has performed flawlessly for nearly 100 dives:

I have used G-Shocks exclusively since they hit the market. They have been virtually trouble free. One of mine, which was almost never rinsed in fresh water, developed a "stickiness" in the buttons. I suspect that was from salt buildup. I have never had one to 200 meters, but the ones I have owned have been water tight to ~200 feet.

This is the one I have used since 1998. I have purchased many other watches and continue to go to this one. It just performs and keeps on going.

I also use a GS and have had no problems. I also have purchased like for just $10 or so a watch from WalMart called the Aqua something or other. It works fine and I sometimes buy a couple before a dive trip and hand them out as gifts to DMs or helpers.

I also rocked a G-shock for like a million year. I don't think I ever had to change the Battery either lol

This gets my vote as well. My original (circa 1991) gave up the ghost two years ago in Bonaire, forcing me to finally invest in another one.

For price, functionality & durabily, I don't think you can beat it.

FWIW, I use it as a backup to my dive computer, but I could just as easily use it on its own with tables.
