Casio TS-200 (Black) – Restoration

The story of this Casio TS-200 (Black) started the same way as many good vintage Casio projects 😅. On a Facebook group called The Casio Vintage Club, someone tagged me under a post. A collector from Sweden was selling a larger lot of Casio watches from the 80s and 90s. All of them were not working. Most were in average condition.

For many people, it was just a box of dead watches. For me, it looked like a great opportunity for restoration projects. I chose six models, sent an offer, and we quickly made a deal. The package arrived very fast, and the work could begin ⌚.

The first watch from this lot was already restored, the TGW-10. The next one on my bench was the Casio TS-200 (Black). This model always caught my attention. It is an early Casio sensor watch with a built-in temperature sensor and a very strong 90s tech feeling. I already restored the white version before, so working on the black version felt familiar, but still exciting 👍. Sensor models are a bit different, a bit quirky, and that is exactly why collectors like them.

What was the initial condition of the watch?

At first look, the Casio TS-200 (Black) was exactly what you expect from a watch that spent decades in a drawer ⌚. It was not working. The resin case was scratched, and the acrylic crystal had visible wear. Dirt was stuck in the gaps and around the edges. The watch also had no strap, which is very common with this model.

Structurally, the situation was good 👍. There were no broken lugs and no cracks in the case. This is very important with the TS-200, because the case shape is not easy to repair. After opening the caseback, I found an original Toshiba battery made in Japan. This was a good sign. It usually means the watch was never opened before. There was no corrosion, and the module looked clean and untouched. The outside needed work, but the heart of the Casio TS-200 looked promising.

Does the module still work? First power test

The next step was checking the module 🔧. I always do this before any cosmetic work. There is no reason to sand a case if the electronics are dead. I installed a fresh battery. After that, I performed a standard AC reset, which is necessary for old Casio modules after long storage.

The result came instantly 😅. The display showed 12:00 right away. Full LCD. No missing segments. All buttons worked as they should. At that moment, I knew this restoration would be straightforward. A working module, no broken lugs, and no cracks in the case is the best starting point you can get with a vintage Casio TS-200 ⌚.

Restoration process

Once I confirmed that the module was healthy, I moved to the case and crystal 🛠️. This is where most of the time is spent with a Casio TS-200, especially because of its construction.

Step 1: Case disassembly and deep cleaning

I fully disassembled the case. This model has a removable front panel, and the temperature sensor sits close to this area. Dust and dirt love to collect there. I cleaned every part carefully to remove old grime from the gaps, edges, and sensor area. This step is important. If you skip it, dirt stays trapped inside forever.

Step 2: Sanding the resin case

Next, I started sanding the resin case.
I used sandpaper from 1000 grit to 2500 grit. I worked slowly and evenly, always checking the surface. The goal was simple. Remove scratches and keep the original matte finish. Resin cases are easy to overdo, so patience matters here 😅.

Step 3: Acrylic crystal restoration

After the case, I moved to the acrylic crystal ⌚.
I sanded it up to 7000 grit to remove deeper scratches. Then I polished it using felt and Polywatch. This brought back clarity without changing the shape of the crystal. This step always feels rewarding.

Step 4: Final case finish

To finish the case, I used a white magic sponge.
First dry, then slightly wet. This gave the resin a clean, even, factory-like matte texture. At this stage, the watch already looked alive again 👍.

Step 5: Strap selection

The last step was the strap. The original strap for the Casio TS-200 is very hard to find today and often expensive on eBay. This model also uses uncommon dimensions, 17 mm lugs and 22 mm fork width. I used a proven replacement strap from Casio CA-56, DB-V30, DBC-V50, and LDF-40 models. I tested this solution before on the white TS-200, and it fits perfectly here as well 🔧.

The final result

After reassembly, the Casio TS-200 (Black) came together exactly how I hoped ⌚. The resin case looks clean and even, with a proper matte finish close to the original. The acrylic crystal is clear again, without deep scratches or haze. It still looks vintage, not over-polished, which was very important for this model 👍.

Technically, the watch works 100%. The module runs perfectly. The temperature sensor, sound, and all functions respond as they should. With the replacement strap fitted, the proportions look right on the wrist, and the watch feels comfortable and balanced. This TS-200 is no longer a forgotten drawer piece. It is fully wearable again and ready for many more years of use 🛠️.

Restorations like this show why early Casio sensor watches are worth saving. Simple construction, clever ideas, and strong 90s character. Exactly the kind of Casio that makes this hobby so addictive 😅.
