After connecting to iphone, Apple Watch fails to download watch os

Hello everybody 🙂

Yesterday i got an Apple Watch Series 1 *second generaton*, 42 mm. I connected it to my iphone and then it said i had to download the latest watch os software. I wanted to download it at night, but in the morning it wasn’t even finished yet so i canelled it. I restarted me Iphone as well as my Apple Watch, but the results are the same. For longer than 1 hour it says the download time of watch os 4.2.3 is 1 hour, and after some longer time it chances to 1 day or even 4 days. My internet connection is not that slow and i usually have no problems updating iphone or ipad. Right now it is updating since 8 in the morning and now it is 13.48 in the afternoon... the process is minimal and extremely slow.

What can I do... Has anybody similar experiences

thank you very much
