This is not really a change. Do you want to extend your mobile contract and buy a watch at the same time? Otherwise you can just buy the watch separately. There is no discount for buying a watch together with a mobile contract extension so it doesn't make any difference.

@Aaku Good Morning, I would buy the watch somewhere else if the offer is not available here on O₂. And you usually don't get a discount when you buy a device + contract. Maybe you can get it cheaper if you buy the watch from MediaMarkt or similar.

Hello and welcome to the community @Aaku. 

You can order smartwatches directly without tariffs, if you wish.

Or should this involve a contract extension with your current tariff?
