Beyond that, Sindome is it's own take on the Cyberpunk Genre with it's own lore and history. So we have no reason to do things the same way some other Cyberpunk setting did or does it. I have no interest in engaging in a Cyberpunk lore dick waving contest for every change we might or might not make. Just not going to do it.
If we have different levels of a type of item we want there to be reasons why you might want a more expensive model over a cheaper one. This is a simple way to make that more expensive watch more attractive to your character. So it is fine as is.
