I have often admired the wonderful movements and functions of Casio watches, but wished that the watch cases were more to my liking. What to do? I decided to select an appropriate watch and try building a case that suits my taste.
The watch I selected is the Casio AQ160W-7B. I like the Ana-Digi face with super large positive digits. On the on the hand, I don’t care for the case styling or band. I bought one and saved every part the could be reused in my project: the movement, case back, bezel, and case pushers. The rest went in the parts box.
Next I machined up a prototype case in gray plastic. It is 40mm in diameter and will probably end up relatively thick, 12mm or so, to hold the very thick Casio movement. You can see several photos of the plastic prototype. The crystal will be inserted from the back. The Casio back, held in place with four screws will also be re used. The pushers will be challenging, but I will face that issue at a later date.
Many details are yet to be worked out, but I an beginning the actual build in stainless steel, and I thought some of you might like to follow along on this journey.
