I of course as a poor man do not own any MRG, so I will let other MRG owners here to chime in for their actual experience.

But from the best picture I could find below, it pretty much confirms what you said that the lug screw is proprietary. Given the price of the watch, you don't wanna risk damaging it. I guess you have to send to Casio for any service, including replacing the strap.

 

It looks like Torx, but I'm not sure. Love the watch @Terry M.!

 

Yeah, looks like a Torx head. Pretty easy to get hold of a Torx screwdriver. Just make sure you buy exactly the right size!

 

It requires a special torx driver from Casio to change the strap. The AD needs to order it from Casio if they don't have it.

 

It is a torx driver, you can buy a torx driver set which should have the right size. Just check then double check before trying to remove.

 

There are some members in a Swedish forum that have changed the rubber strap on their mrg-g2000r. The dealer needed to order a special torx tool from Casio in order to change the strap. It's not a regular torx driver that you can buy from a tool shop. The OP has already tried with 4 different watchmakers with no luck.

 

Contact Casio directly, they're usually pretty helpful.. I hope none of those watchmakers stripped any of your screws trying sizes..

 

Sorry for the bump but was wondering if anyone ever found out how to change these rubber straps? I’m running into the same issue as the OP.

 

I have the B2000R-1A and it’s on the stock rubber strap. I have purchased the DLC Ti bracelet but after going to 4 different watchmakers today no one could change the strap for me due to the tool it takes apparently. Many thought it was an Allen wrench but alas it is not or so I’m told.
Can anyone help me out? I did a search but turned up nothing.
Thank you all in advance.

I can take a crack it if you want. Im in the houston texas area

 

Any more updates here? (1) is it in fact a standard torx? (2) Do bracelet and rubber share the same screw to hold on? (3) If you want to go the other way from bracelet to rubber is all you need to buy the rubber and the clasp?

 

Diffrent screws.: LR delta screws. About 200$. U need the rubbers and clasp. But theirs a tiny metal part that can't be purchased. without this part/the rubber straps easily disconnect from the clasp with heavy use. Best bet is to swap with someone who has an mrg with rubber straps.

I have a metal bracelet from an MRG1000dc if anyone is willing to trade for somerubber strap and clasp

 

 

I actually made one a few years back..and sold it about a year ago. That was before I realized they had stopped selling.the clip that holds clasp to strap 😪

 

I still haven’t been able to change my strap to metal cause of the LR screw. Can’t find a tool to get the LR screw/bolt off.

 

You guys need to take a better pic of that screw head lol!

BTW my Wiha sets have some funky looking bits.

 

If anyone is interested, I have an MRGG1000DC band to trade for rubber straps. I can remove them for yall if interested. I spent about 600$ making a custom CNC tool to remove the LR delta screws.

Maybe you could sell the tool instead?

The reason I am interested in this, is I was trying to decide whether to get a MTG or MRG, and ability to swap bands makes the proposition of spending that kind of money more palitable. My intutition is the current crop of MRG and their cases must be nearing end of life. I'm going to get a MTG and see what happens if and when Casio update the MRG. Not that Casio have covered themselves in glory in the MTG band situation either, but at least the price is less.

 

The current MTG toolless strap and bracelet removal is brilliant. Granted you're still kind of stuck with Casio's proprietary straps, but I only wear mine on bracelet anyway. I'm hoping they eventually start offering more straps since the whole system is so incredibly convenient and pretty much designed for swapping and having fun.

Never heard of litigation?

 

 

That metal piece (tip of screw driver). That's what piece u need in order to keep the band in place;without it,it'll come off with harsh/sudden movements. Pacparts/or casio won't sell this piece

 

So basically to remove it your tool works like a security torx but backwards, meaning the need to grip and undo that center triangular shape bit which essentially holds the bar in place, yet the outer rim of the driver is torx in order to fit.

What was Casio thinking lol!

 

This is how it works.

I got about $398.00 wrapped up in this tool. I'd let it go for that + shipping. I can rent it out to you for 50$. With a $398 deposit/you'll get that money back once u return the tool
