I'm currently visiting family in Germany while also trying to do remote work and these two items are saving me:

European Travel Plug Adapter, FOVAL EU/UK/US Power Strip with USB C and 4 USB Ports, This isn't something that I'd buy if I was traveling light but since I need to hook up multiple items, this power strip adapter is doing really well for me.

Huawei Unlocked Mobile WiFi Hotspot--this hotspot is seriously amazing. It's super small and lightweight so I've actually been throwing it into my crossbody bag while I walk around. You do have to buy a SIM card to use it but those are pretty affordable and easy to buy here.

You can try carrying a hotpot device in your pocket and have Apple watch connect to hotspot's wifi. for example https://www.amazon.com/Huawei-E5576-320-Hotspot-150Mbps-Download/dp/B07Z5LWMNZ/ref=sr_1_16?crid=302PDMXRG9PST&keywords=hotspot&qid=1665254018&qu=eyJxc2MiOiI1LjU4IiwicXNhIjoiNS4xOCIsInFzcCI6IjQuNzIifQ%3D%3D&sprefix=hotspot%2Caps%2C311&sr=8-16&ufe=app_do%3Aamzn1.fos.006c50ae-5d4c-4777-9bc0-4513d670b6bc
