CNC Case F-91W · 模型 167885
This has been a passion project for me. I have learned so much in developing this watch and am currently developing this watch further. The goal was to make a metal case for the F-91W. Currently due to the limitation of the manufacturing methods available to me this watch was made using CNC milling. I have sourced all the parts for this watch and or designed them. I am releasing this design and another similar design so that people can iterate upon this. This is not a final product as it is still very much in development. The watch was designed to take a 28 mm sapphire crystal and to use modified Cassio A171WE buttons. The gaskets were obtained from a g-shock button replacement kit. The crystal was secured with B-700 glue. I am still exploring options to not use this glue but rather a gasket. The back gasket is taken from the A171WE. To modify the buttons some sanding needs to be done as the buttons are 2.5 mm in diameter. CNC mills do not go to 0.01 mm increments and makes machining a 0.02 mm clearance expensive. To avoid this I just sanded the buttons down to 2.48 mm. The face plate and ring will be separate parts and will be published independently. I used the model provided and the drawing provided to get my design manufactured with PCB_way. The cost to manufacture bare bones is around $60. I live in the states and got it shipped for around $30. Making just the case $90. The screws for the backplate were selected to be standard M1.4 x 0.3 x 3. In the drawing it is specified to go 3 mm in depth, but they might be off. I ordered the screws from amazon. If there is popular demand. Will explain everything in detail in a YouTube video. If you read this far thanks.
