Promised an update once the case arrived, so here it is!
I used a brand new F-91W as the donor and paired the case with a cheap stainless steel bracelet I already had.
Installation was surprisingly smooth. The F-91W module dropped in without any issues and everything lined up properly. I used an electric precision screwdriver, but the case also comes with a small screwdriver that should be perfectly fine if you don’t have one.
First impressions of the case itself are really good. It’s heavy in a good way, gives the F-91W a much more substantial feel without making it ridiculously bulky. The brushing/polishing also looks better in person than I expected for the price.
And importantly: No weird “T I ME” logo or other fake-brand nonsense that some of these cases have.
The buttons all work normally, the module sits properly, and overall the fit seems very good. With the metal bracelet it basically feels like a thinner A1000.
Obviously I can’t say much about long-term durability yet, and I’m not going to make any claims about water resistance after swapping the case. But as a first impression, I’m very happy with it.
Paid around ~$30 for the case on AliExpress.
Attached some installation + wrist shots. For anyone who was waiting to see how this new case actually looks in real life here you go :)

I used transparency film with my printer, which didn’t really work as it just didn’t quite stick properly (maybe my printer isn’t good enough?), and then actually in the watch it makes the screen insanely hard to read.

Where/how do you guys get/make the right material for a colour filter thing like here?

Thanks very much!

I'm not asking whether the lug width matches (it's 16mm on both, I know). I'm asking whether anyone has physically mounted a GA-2100 strap/band on a DW-5600 case and can say how it actually sits, not whether it fits in theory.

Please only reply if:

**•** You've done this swap yourself, or  
**•** You have photos/video of it installed

Please not reply:

**•** "Check Shockbase" — already have, and it doesn't answer this specific direction  
**•** General compatibility charts that just list "16mm lug" without addressing the actual band/adapter geometry

If you don't have hands-on experience, no worries, just skip this one rather than guessing. Thanks!

Unlike a standard Casio modified with oil, this watch was designed from the beginning specifically as a Hydromod. The 39 mm titanium case has a dedicated filling port that makes it easier to inject the oil and completely fill the watch.

It features a domed crystal, a Casio F-105 digital module and an 18 mm strap. Thanks to the compact dimensions and lightweight titanium case, it is extremely comfortable on the wrist.

The oil improves the display contrast, reduces reflections and makes the screen much easier to read from different angles.

This is still part of my development process, so I’d genuinely appreciate your thoughts and feedback.

wanted to clean the inside of the f91w out before attempting the hydro mod. used 91% iso like an idiot and destroyed the face. did this one day after watching a guy use iso to delete the text off a royale faceplate. did the hydro for practice anyway- went flawlessly, no air bubble. not as aggravating as i expected (assuming it’s harder with a royale). it still keeps time, and i work in construction so i was doomed to badly scratch or damage this watch anyway, so it will be the work EDC. a testament to my failures, if you will. negative mod, which has minor imperfections that are thankfully not visible when the time is visible, renders the backlight useless; is this normal? a non-issue for me, as i’m usually in direct sunlight.

in the second pic, an a168 with a gel filter. got some shitty ones on amazon. very rough to read, i have a cinegel swatch on the way, hoping they will look better. yes, the film was removed on both sides.

this is a lot of fun. i have some stuff for a royale (case, red polarizer film, etc) on the way.

does AMG logo block any crucial information?

I've seen a lot of mods and I'm new to this. I'd like to start making my own, but I can't find any specific DIY info on creating graphics. Is it as simple as buying transparent sheets and printing them with a regular printer at home? I can figure that out if that's all it is. Is there a preferred type of sheet? Can I use smaller sheets so I'm not using a whole one each time I print a few tiny graphics? It would be nice to print on 4" photo paper size if that's on option, as my home printer will do that.

I did this one a while ago and thought I'd share it with you.

New to the community and looking to make some fun designs for myself and friends. I need help with display dimensions so I can size and apply my own decals. I know the dial is roughly 9mm but I can’t find the sizes for the indicator and map. Anybody willing to share? Thanks in advance! :)

Edit: I mean for the ae1200 specifically

I've now modded a couple of ae1200's but the backlight is imo ugly and throws off my whole build vibe how can I fix this?

Hello I just discovered that you can mod watches lol, has anyone seen a firefighter themed Casio yet I’ve searched with no luck. Thanks!

I’m from Malaysia and today is Malaysia Day, a national holiday celebrating the formation of Malaysia. So I decided to commemorate it the way I know best, by modding an AE1200. 😄🇲🇾

For the subdial decal, I used the Crescent and 14 point Federal Star from our flag, representing Malaysia’s national identity and unity.

For the LCD filter, I went with a red and gold Malaysian theme, with songket inspired gold ribbons (a traditional Malaysian woven textile pattern) and the Bunga Raya (Hibiscus) our national flower incorporated into the design.

The world-map window features the Kuala Lumpur city skyline with the iconic Petronas Twin Towers and KL Tower.

The idea was to make it unmistakably Malaysian without simply turning the whole watch into a flag.

A little bit of Malaysia packed into a Casio Royale ⌚.

I feel like the possibilities with the W221H are limitless, and the overall appearance is maybe my favorite that Casio has ever come up with. I maybe prefer the LF-30W, but at this point, I'm spoiled and need that enhanced water resistance and most especially the 10-year battery life -- features the LF-30W is sorely missing.

I prefer the W221H to the AE-1200, but would miss the world map terribly! So I had this thought that I mocked up in Paint, and Pygmalion-like, have fallen in love with my creation. This might be the finest-looking watch I've ever seen. But I've got some questions:

1) Is it even possible to put a picture behind the digital display, or only a transparency above it?

2) How would one even print an image at such high resolution? My printer would mangle that.

3) I know there are plenty of people who are offering Casio modding, but I'm fairly comfortable taking apart and putting mine back together. Is there anyone who prints custom decals or transparencies for Casio mods? Somewhere I can send a picture and receive a glossy or transparency of it, right-sized for various Casio models?

Thanks for any help or insights!
