But it's been fascinating to see, over the years, how many times I've been approached (in a coffee shop or some other public place) by serious Casio enthusiasts, keen to ask about my watch and to show theirs. There's so many variations, colours, limited-runs editions... I seem to have accidentally stumbled into a niche with lots of passionate hobbyists - I'm sort of glad I had to replace the awful strap, which snapped, so I actually have something to contribute to the conversation. I had no idea Casio watches were such a big thing, but now I'm not at all surprised there are modding projects like this.
