Make a wristwatch out of a calculator

Making a wristwatch out of a calculator or any other machine would require some technical skills and modifications. While it's not a typical DIY project, here's a general outline of the steps you could follow:

Select a suitable calculator:

Choose a calculator with a small form factor that can be comfortably worn on your wrist. Look for one that has a clear and readable display.

Disassemble the calculator:

Carefully open up the calculator, taking note of how the internal components are arranged. You may need to remove the housing, buttons, and any unnecessary parts to make it smaller and lighter.
