Black Blurple Mudman
19 January 2021redrockflycaster

originally posted on ebay.com

Considering this is a rare color version, and very pricey when you can find one, I got lucky and got one at a pre-owned price, that was in excellent condition and only needed a battery. Changed battery, added watch silicone grease to the O-ring, and watch is good as new. If you keep an eye out for a used one like I did, you can add this to your muddy collection, without having to spend the crazy prices some folks want for it. Parts are still available from Pac Parts, if you get one that needs a new bezel, band, O-ring, screws. I ordered from them, for other mudman watches I own, and it takes awhile to get them, but worth the wait.

Recently bought this with pound accrued through previous purchases for a trip to the beach. The buttons were a little hard to push at first but over the week they became easier. I had a Apple Watch which I gave to my son because I was tired of being overly mindful of my watch. This dose what I need it to do tell time and take a beating in the process!

Great

Great watch. I bought this watch for my 17yo son and he loves it. Chunky modern look and fits perfectly. His mates always comment on it.

Nice men’s watch. The gold accents add a bit of shine to an ordinary shorts watch. It’s versatile within a wardrobe. Great accessory!

Nice watch
7 April 2024

Husband like it a lot he just said that he wishes the light was brighter because it’s very low and makes seeing hard and he has 20/20 vision but he really liked the shiny strap he says it’s more comfortable than wearing the silicone strap

Very Nice Watch, recommended 👍🏼
7 January 2024

Bought this for my teenage Son for Christmas, he is obsessed with watches & loves the Casio G-Shock watches. This is a beautiful watch & it comes in a nice metal box for gifting, I personally would highly recommend it, my Son absolutely loved it, I had wrapped it & put it inside his stocking, he was not expecting a watch in his stocking; I like to keep my kids guessing. This watch is solar powered & honestly all the Casio G-Shock watches my Son owns are very nice, he really loves 🩷 this watch.
