Casio74243710 Genuine Factory Replacement Parts fits DW-5600, DW-6900, G-5700, GA-100, GDF-100, GL-7200 and GLS-5600 Series

I really like the durability of G-Shocks but I have always hated the resin bands. I put this adapter on a GA-800 and it looks great! I was concerned in the beginning because of the angle of the adapters but once I put the 24mm NATO strap on it and put it on it felt much better than I thought it was going to. It does not dig into my wrist at all. I'm glad that I bought this and I like that it's made by Casio. I was going to buy a Jays&Kays adapter but as soon as I saw that Casio made their own I gravitated to them.The product comes with 2 16mm spring bars, I did not need these because I just used the spring bars that were in my watch but its cool that it comes with replacements in case yours are broken/lost. It also comes with a spring bar tool. I already had a spring bar tool that was longer so I just used that because of the leverage. If you buy this it comes with everything you need to do the job.My only complaint is that the spring bars are very difficult to put in and difficult to know if they are fully inserted. It took me a couple of times to get it to stay but once it was in I pulled on it and tried to move it around and it stayed. I haven't had any issues since installing the adapters.If you hate the straps G-Shocks come with I highly recommend this adapter. If I buy another G-Shock I will definitely get this again.

These seemed to be exactly what I wanted to permit the installation of a leather band, but did not fit the G-Shock model I bought them for. I have since learned that Casio does not sell a leather band conversion for many of the newer G-Shock models, so I returned these items, and will keep looking for a different solution.

Total junk. I am not talking about the fit, I am talking about how much of a PITA it is to change the spring with a g-shock. Seriously, just buy a new watch. Do not waste your time or effort trying to replace the band with these adapters. My old band broke on one side and I had to rip the other side out because the spring would not come loose. You cannot get the tool in properly to replace the spring with these adapters. G-shock has gone through A LOT of trouble to make their bands nearly impossible to change so they can make profit off you buying another watch. The same goes for the exact band for the watch, same problem. Too much hassle and not worth the effort. Just buy a new watch, and not a g-shock. I had mine since 2015, but it has always had some problems so I will never go with g-shock again.

For the quality of this adapter, it is well made and does the job. I originally did not realize it WILL NOT fit with the non spring bar type watch case using the screws. There is no possible way I can use it with the Mud-Man and some other types in the Pro-Treck series watches that I have.I tried to order the type of adapter that fits with the other type using the screws. Apparently, they will not ship to Canada. I called Casio. They told me this product is not theirs. They can only supply the original watch band for their watches.I gave this adapter five (5) stars because it is a very good adapter. I have a few Casio watches that use the spring bar type mount, and therefore this adapter will fit to them very well. If you search out on YouTube there are some excellent videos about this type of adapter and how to use it with a NATO band. If you have a Casio model that complies to the fit of this adapter it will do the job very well.

These adapters are way too expensive for what you get and how much effort it takes to fit on a G-shock. They're just pieces of rubber that are way too large for any watch. In order to fit them in a G-shock, the sides of the joint need to be sanded down. I've attached a picture that shows where to sand.If these things were a couple of dollars, they might be worth it. Unfortunately, at their cost you might as well spend a little bit more for a jaysandkays adapter. I cannot recommend these adapters for any watch, even if they didn't need to be filed down.

Install was a struggle, and the stock spring bars are too thick. With smaller diameter spring bars and an iron will, you can really help out your G-Shock. You need to lay the watch on the face and install the adapters as they lay flat. A second pair of hands and two spring bar tools might help, but patience and tenacity can get it done.Once they're on, you will want an RAF strap or a NATO without the keeper, because the keeper loop will tighten against the adapter and lift the watch off your wrist.

Rubbish fitment and production standards. Used proper tools for what felt like an hour and finally was able to seat the pins but not until damaging a literally brand new DW5600 in the process. And had to shave off some of the adapter to do that. Only reason not a 1 star review is that they do actually work for the purpose if you persevere.

Looks great. Functions great. Let me say after an hour of installing, this is very, very difficult to install because the hard rubber or plastic needs to be deformed significantly to install on the watch case. The only way to do this is to push very, very hard on the little steel pins. I had the right tools but that didn't help. Let me repeat: It took an hour.

As advertised.Works great.

取り付けが難しいことは覚悟していたので２０分ほど格闘しましたが削るのは嫌だったので時計屋さんに持ち込みました。「すぐつけますよ」と言った時計屋さんすら「やはり少しお時間をいただいてもよろしいでしょうか？」とおっしゃったので難易度はかなり高いと思います。（ちなみに適合モデルです）とはいえ、つけた感じは素晴らしいです。ベルトをつけかえる楽しみもあるのでおすすめです。

Only received one of the two adapters I paid for. Very disappointed!!!

G-SHOCK AWG-M100B-1ACR の純正ベルトが長過ぎ、収まり悪く不満だったことから、NATOベルトを使用すべく本アダプタを購入しました。商品説明によると適合外でしたが同機種で成功されたtakuさんのレビューに後押しされました。ベルト交換は成功したものの、想像以上に困難な作業でした。何故ならば、見えない位置にバネ棒を固定させなければならず、またアダプタの干渉部が不明確な為、戸惑いつつも他の方の貴重なレビューを参考に手探りで作業しました。結果、片方を固定するのに三時間以上要しました。正直、最後は神頼みでした。これはいけると確信したものの、結局、両方の装着には五時間以上、二日にわたる作業でした。最後は執念… なお、完璧な処理を望まれるならば、カッターの他に平ヤスリが必要です。紙ヤスリでも良いですが断面を平面にするのが難しいと思います。またバネ棒用工具も必須ですが付属品で十分です。U側を多用しました。私はアダプタを２セット購入、あわよくばBABY- Gに使用出来ないかと目論みましたがバネ棒の長さが異なり使用不可。そこで一つを試作用としました。ぶっつけ本番では仕上りの完成度が低いかも知れません。何故ならば、試行錯誤でアダプタを大きく削る必要があり、加工した部位のどこが見た目に影響するのかを見極める必要があるので、適合外G-SHOCKでのご検討の方は予備品も購入されることをお勧めします。苦労して手に入れたMIL-SHOCKは最高です。多分に自画自賛ですが… しかし新品だった時計には作業過程で裏面のバネ固定部上部に無惨な傷痕？ いや名誉の傷痕？ が多々残りました。ほぼ隠れる所ですから私はあまり気にしませんが、細かな方はご注意を。途中、力を入れ過ぎたり、バネ棒固定穴を潰してしまいそうであり、バネ固定部が意図せず削れてしまうため、本体が壊れるのではないか、新品をこんな状態にしてしまい、もはや引き返せず私は一体何をどうしたいのかなどと煩悶しましたが、終わり良ければすべて良し。そんな訳で繰り返しますが、適合外のG-SHOCKだとかなり難易度高く手間がかかることを覚悟の上、全て自己責任で挑戦して下さい。その対価は十分あると考えます。ご健闘を祈ります。NATOベルトはその日の気分で手軽に色を変えられるので楽しめます。私はブレスレットの色に合わせて使用します。

質感が安っぽくて、すぐ飽きた
