To preface, I’ve never owned an Apple Watch.

Planning to buy a new SE Apple Watch GPS, mainly would be using it for walking directions as I’ll be travelling soon and would like the ease of access getting around with a watch not having to look at my phone for directions.

Can you use the watch to get directions from trains and buses, is it accurate?

I don’t wanna spend money on this watch if it can’t get me around efficiently.

Appreciate any replies.
