It was your mention of G-shock that prompted me to think about this method of storing seed phrases.
Advantage of using a watch is that you can easily have it on your wrist, and almost nobody would suspect what you have hidden inside it.I have been trying to find other wristwatches that could be work in similar way, without being a smart watch, but no luck so far.
Maybe that is not a bad thing, there are plenty of G2900 available in Japan and worldwide.
Curious, does Casio (or another) produce watches with memory cells now? Smart watches are not considered
As far as I know there are no more G-shock models in production that have Data Memory.There are other models but they have smaller memory compared to G-2900.
You can check them all here:

There are several Casio Databank models but I am not sure how big their memory is:
https://en.wikipedia.org/wiki/Casio_Databank
What memory does this watch use? Autonomous? If the battery is removed, discharged (as the manufacturer assured, the battery life is 10 years
) or is damaged due to physical impacts, then the internal memory data will probably disappear forever.They use cheap CR2025 battery that lasts for years with no problem, but when removed it's all gone, that could be a good thing also
Casio gave it 10 year rating, but people say it lasts longer if you don't play with watch and light all the time.
