I bought a light purple watch on TEMU. It was poor quality. The band broke. The buckle broke. The led blinded you so you cannot read the time. The worst, it wasn't accurate.
I fixed the band by tape underneath. I reconstructed the buckle with 1.2 mm iron wire. I screened the LED by Al foil. Where else can you can get a watch with such a fantastic color?
Then the difficult part. I have a dozen or so broken watches, not all digital, the oldest one is what my father got on the Saint Nicholas day 1922. The Casio's are the best, but the connection with the band to the case breaks all the time, and they get more complicated over time. My purply is ideal: 3 buttons. Set time, switch time setting&light, and switch to stopwatch.
I cannibalized on of the Casio's. They are higher quality. The tiny 1.5 mm screws are anti-magnetic. The plungers that go through the case (to activate contact) are secured by segher rings, I kid you not. The crystal has a higher accuracy.
Then the crystal on my purple watch was replaced by the Casio's crystal.
(Never mind that gluing the Al foil I knocked over a bottle of cyanoacrilate glue. The cleaning up took more time as the rest of the operation.)
