It’s not an all-3 charger, but I just bought a Belkin combined iPhone/Watch charger and it came with its own Watch puck built-in. It’s surprisingly difficult to find combined chargers that come like that. (I’m not really answering your question, more just commiserating with you)’
I’ve been using Nomad’s since the beginning of April with no issues other than if a magazine or cord gets under the watch band, it can separate the watch from the charger. Hasn’t been an issue since I decluttered my nightstand, though. I can’t say if it’s the right one, but it’s not something I have to think about anymore, so it’s not bad.
They just refreshed it to add USB outputs and faster charging (and bump the price a bit.)
