My Quest to Mod my Casio MDV106 Pt. 3

So, if you aren't aware of the journey I have been on with my Casio Duro, check out Part One and Part Two.

Adding a sapphire crystal to my MDV106 went fantastically so I felt confident enough to try it again on a second Duro I had sitting in the closet. I purchased this one back in October 2022 and pulled out the crown in order to prolong the battery life.

The crystal I used this time was a single-domed sapphire with bluish AR coating. I purchased this from AliExpress, just like the first crystal.

The process is straight forward and I didn't need to refer back to Jody's YouTube video for help. Honestly, it is simple enough for anyone who is comfortable removing the case back of any of their other watches. Factor in the reasonably low cost of a Casio Duro, and the pressure to get it right is all but nonexistent.

Check out the photos I took during the process, as well as a short YouTube video I made that shows the crystal distortion of the domed sapphire. I'm ordering a cheap jubilee style bracelet from Amazon for this watch as well.

Let me know what you think and what your experience is with modding on of Casio's most respected and revered watches.

Try the hands next. 1.20mm / .70mm / .17mm will be hard to find but not impossible

I am willing to give it a go. I鈥檝e never done it, but I gotta start somewhere. Have you replaced the hands before? If so, how difficult was it?

Hi, I changed the crystal pretty much same route as you (AliExpress) it was a piece of cake however when the old one pops out the crack sound is a little disconcerting 馃槀

I am considering modding it later with as suggested different hands but I鈥檝e just replaced a miyota 2035 in one of my wife鈥檚 storm watches and this was my first experience refitting hands to say it鈥檚 fine work is an understatement!! Well done sir 馃憦馃徎馃憦馃徎

Youtube is your friend with watch modding. Its easy with minimal tools. Substitute Sticky-tack for Rodico and use it to pick up and place most all the small parts. Tweezers launch the little things to Narnia. Poke the hand into a pointed piece of sticky tack the size of a pencil and use it to position the hand. Use a pen with the refill removed to set it then. I have a few drilled out for the different sized hands. Perrin(Canada) or essinger (US) are the best with Aliexpress for some but mostly Seiko stuff.

Did you need any sort of magnification to assist you? I'm very interested in disassembly/reassembly and I have a couple of movements I fudged up trying to regulate them, so it wouldn't be a huge loss if it took a while to figure it out.

You do need magnification to do the hands, I have loupe鈥檚 and a desktop magnifying glass but the best method I have found is the head mounted magnifier ( pic attached) it鈥檚 good for the job but the mounting pin for a second hand is still barely visible and a struggle to fit initially

BTW I am an amateur watch "tinkerer" my kids brought me lifelong subscription to this channel. I鈥檓 doing watchmaking 101 it鈥檚 run by Christian Lass who is a curator of PATEK PHILLIPES museum it鈥檚 a very good course broken down into bite size sessions regarding mechanical movement de assembly and reassembly

There are some free sessions if you want to try before you buy馃憤馃徎

So true!! 馃槀

Just modded my 106 Batman and 107 Pepsi. AR Blue/Red Double dome. Had to watch Jody's tutorial on how to remove the crown again. Kept pressing the wrong lever. Did the 106 first. Chapterring fell off and moved around when putting the movement back. But made it at the end. The Pepsi was I think record time.
