What's the story behind the first watch you designed for Casio, the F-91W? By the time I designed the watch, I had spent four years with the company. Back in the late 1980s, market segmentation for digital watches was very distinct with regards to features and price points. The F-91W had to fulfil certain criteria with a set strategy and I was determined to make it work. Design-wise, it started with me trying to adapt to the circular shape of the battery, which is flat and wide, and the quartz module, which is octagonal and slightly smaller than the battery. Those were the limitations I had to work around, but I still wanted a watch that is small, flat, simple but well-designed.
To me, the most beautiful part of the watch is its angular bezel . We went through about four prototypes before arriving at the final version. I've design many watches since but the F-91W has proven to be really enduring...
I enjoy family life, the outdoors and working with my hands.
That's a good article!
