My casio watch is waterproof. [100M Water Resistant]
And it has a user replacable battery.
With a gasket inside and cool looking screws. (yes, I consider screws to be cool)
Also, it costs less than $20
Your Casio watch also has a manual with a warning inside saying it won’t be waterproof anymore after a battery replacement unless you send it in to Casio to replace the battery.
