Richie strap] 24mm 3 Ring Nylon Watch Band Strap Metal Adapters Kit for Casio GShock G-SHOCK Big Mud GWG-1000GB GWG-1000-1A/A3/1A1/GG

As other reviewers have said the holes don't match up. This will not work on a mudmaster

It messed up my watch !!!!!

Just like the other reviewer, I had to enlarge the guide pin hole to the proper diameter (1.1mm) with a jewelers drill for it to fit but upon attaching it to the base of the Mudmaster watch, the guide pin hole still didn't match up. I had to enlarge it much further so guide pin would finally align. These adapters should be test fit on an actual watch prior to shipment from the producer. For $10 I'm not going to complain. If you don't want to use the guide pins and just the two main screws per side, that should still work as the two main screws are secure enough to hold the adapter to the watch base. If you want it proper, you'll need to enlarge the guide pin holes.

It’s cheap. As in cheaply made and the holes don’t all line up plus the Guide pin holes are too small. I’d give it one star if it wasn’t for convenience of it being available on amazon prime and the fact I’ve got jewelers sized drill bits to correct hole alignment. So if you’ve got tools then sure it’s worth it for the price but if you’re expecting it to fit the mud master Iggy out the box then you’ll be disappointed.
