I was looking at the Casio calculator catalogue recently, and I noticed there are a lot of different models. They're all broadly the same, but each one has slightly different combinations of features and appearance. The watch collectors on YouTube show that there's been hundreds of different Casio watches as well. I wonder why they create so many different models. Could it be related to the work culture of the Japanese companies? Or do they just want to have a different product for every use case?
