casio strap adapters for watches that are not g-shock
This used to be something only for G-SHOCK watches, but thanks to lovely people with 3D printers, they're now available for a whole bunch of regular Casio models.
The first strap adapter kit I remember was for the G-SHOCK DW5600E. Without question, the worst part of the watch is that polyurethane resin strap as denoted by PUR on the strap interior.
Being the DW5600E as an entry level G-SHOCK is so popular, and because a lot of people wanted to use a fabric strap (as in nylon), the strap adapter kit was born...
...but only for G-SHOCK watches.
Time passed, more people started getting their hands on 3D printers, and soon enough, strap adapters for regular Casio watch models began appearing. I believe the first was the strap adapter kit for the AE1200 since that is a very popular regular Casio model.
However, as you can see in the above image, a search for casio strap adapter now brings up adapter kits for a whole bunch of different models. The G-SHOCK is included, of course, but so is the F-91W, W217H, F108WH, bigger models like the WS1500, AE1500, DW291H, and so on.
What I'm personally really happy about is that adapters now exist for the WS1600H. This watch is the same size as the AE1200 but way more legible. Big digits for time, date and day and great night light, all in a not-huge size. And since it's basically an AE1200 with a different module, strap adapters exist for it.
Which strap adapter type to get?
Good question, and I have a good answer.
Generally speaking, most strap adapter kits come in two types. Slip-through and band.
Slip-through has a slot on each adapter, meant for one-piece straps, as in NATO or Zulu style.
Band has protruding lugs on each adapter meant for two-piece straps or bracelets.
My favorite part...
...is that you can finally escape the skinny PUR straps Casio uses on so many of their lower cost watches.
For example, you could, if you wanted to, have a Casio F-91W with a 22mm strap. That would look all sorts of ridiculous, but the point is yes, you could do it (although it would be much more sensible and look much better to use 18mm for an F-91W).
Remember that fabric nylon straps do not taper. What that means is that the strap does not get skinnier as it approaches the buckle. The width is the same for the whole strap. Using the F-91W as an example, the stock strap tapers down to a very skinny 16mm, so if you switch over to adapters and use an 18mm NATO, believe me, much better. Gaining 2mm width on a strap may not sound like much, but it does make a noticeable positive difference.
And for larger watches, punching up to 22mm wide is oh-so nice.
You finally have access to the most comfortable watch strap that exists
The most comfortable strap for a watch is the stretchy elastic fabric band. These are primarily made for smartwatches, but guess what? With Casio strap adapters, you can use those straps on a Casio too.
This strap type alone can make a plain Casio digital your favorite watch. If the one thing keeping you from wearing a plain Casio is an uncomfortable stock PUR strap, switching to an elastic fabric type will finally make it comfortable to wear.
Tools needed?
Just one, and if you own a bunch of watches, you may already have it, a spring bar tool. You need that to get the spring bars out to install the strap adapter.
If you don't have one, my suggestion is to get a small watch repair kit. It will come with the spring bar tool, and most will throw in a small bag full of extra spring bars. And you might need that because if that bar goes flying across the room when taking it out, you'll never find it again. Good to have spares.
I should also note it's super cheap just to buy a 360-piece spring bar set if you just need the bars. Again, if you have a bunch of watches and switch out straps every so often, sometimes spring bars go flying and get lost forever. It's totally worth the 6 to 8 bucks to have extra bars.
Does Casio themselves make strap adapters?
Yes, but only for G-SHOCK models. And it's quite the production to even get them. You either have to buy a G-SHOCK that comes with a fabric strap to get the adapters, or have to find a Casio parts supplier that can actually get them for you.
For example, two G-SHOCK models with made-by-Casio adapters on them with a fabric strap are the GM2100C-5A and GM2100CB-3A. On either model, you'll see the strap adapters right there in plain sight.
You either get one of those models, or find an authorized Casio supplier that can put it an order for them. How much for official-from-Casio adapters? I have no idea, but it wouldn't surprise me at all if it ran you $35 or more ordering direct like that.
I only mention this information for Casio watch owners out there that like things to be "100% official". Some just like having everything to come from the original manufacturer.
I'm not so picky. I'm totally okay with third party strap adapters because they do the job, they're very affordable, and they allow me to use something far more comfortable than a stock Casio PUR strap. And I can have it on a regular models that aren't G-SHOCK.
