That is not "user replaceable" by any reasonable definition.
It is interesting to think about the range of physical tool usage that is within a reasonable expectation. Is owning and being able to operate an implement to open and replace a battery in a simple watch like the Casio F91W reasonable?
I do think "turn few screws" is reasonable level of replacement. As long as it is some ISO standard fastener like torx not vendor specific one. We should not require someone to stock increasing variety of screwdrivers based on manufacturers again wanting to make it more annoying
