I am currently trying to learn more about watches and what it takes to build them. I currently own a watch called the G-Shock 7900b and was wondering what runs it inside. Here is a link to the watch:
I am wondering if this uses an ASIC or a FPGA? I looked all over the internet but have had no luck finding an answer. Some of the features include receiving radio signals and having preset dates coded into the watch until 2099. Does this mean that this watch has memory? I always assumed that watches did not have a processor or memory.
Any suggests to these questions?
