Daily notification on watch, synchronised with new but no calendar entry

Hello!

I have a ntification (daily) on my watch, but I cannot find it in my calendar - how can I get rid of it, as I do not need it anymore?

I did change my mobile phone and meanwhile switched from Venu 2s to Fenix 7s but the notification is still there but I cannot find a way to turn it off. Please help!

Thank you!

Greetings,

Tanja
