It's everything a trained Commando wants. Tides, time zones, moon phases with the ability to change time zones easily. Comfortable. No complaints so far.

The watch itself is awesome as all G Shock watches are. Product was as described. I bought this as a gift for my nephew and he loves it. It was half the price if most retail outlets. What has stood out the most about this purchase was the speedy delivery and great communication.

I have always had a g shock. they are tough and durable. New g shock is not as comfortable as the last one and seems to always want to roll to the outside. Never had that happen before with a g shock, but the watch will do what i need it to do.
Bought watches for my boyz, both working as tradies. I was looking for a watch that is tough in construction, provided multiple watch based functions and comfortable to wear. Most G-Shock designs do just that. Boyz are thrilled with their watches and like them, I have 2 G-Shock Mudder in my collection. Watches are simply GREAT ‼️
Recently purchased a Gshock for my nephews 18 birthday. I did a click and collect. It was so easy and the price of the watch was unreal. Nephew loves his new watch. I live in Qld and the lady at the Rutherford store in NSW was very helpful
Love this watch it looks good and it dose everything you could hope for. It feel good on your wrist just a great watch. Like it so much that I had to get two more the same a red one and the black one .
With pleasure expressing acknowledgement of the outstanding customer service and the overall friendly disposition of Walmart and the seller.Needless to say, packaging of the watch was immaculate and neat. The watch was in an absolutely Brand New condition.The reason for the return is, that in reality the watch is much, much smaller then pictured on the website.Nevertheless, despite that and not unexpectedly, we will be associating with Walmart and the seller in the future with pleasure and confidence.Again, many thanks!
This is a non current Casio watch, I wore a black one for years until the band broke. Thankfully eBay vendors still have stock of this rugged watch. There is a non G Shock version available at much lower cost, but I wanted the original. The Tide and Moon data are useful to me daily. Happily on my wrist again!
