We had smart watches before, it was pretty useless since majority of the functions didnt work besides spamming 911 to call the cops. Why would people pay for a device that can already be found through other means like /bank and /bal are commands and you can check coords using f3 or a simple mod for it. There is no registered city per area. The only thing it will likely register is the world your in like wilds, cayman and newcity. There are no set ‘cities’. Lastly if a device like this were to be added, how would this item be of any use besides taking another slot in your inventory. Because besides the fact it is something people will purchase just to collect it has no real use when compared to the other ways of the commands it has. Because if staff were to make a product like this, it should be sell-able to the market so it would need to have an actual real use that the server does not have yet.
