Is it possible to get the battery level of connected smartwatches as part of the Wear API? (Preferably without having to deploy an actual wear-component onto the smartwatch and then communicating back-and-forth between the watch and the device). I've seen some wear-apps that show the battery level of the watch on the watch itself, but I'd simply like to find out the current battery level of the watch using the phone.

When your watch is fully charged, 100% will be displayed on the watch screen and the charging will stop automatically. If the battery level is below 100% and the charger is still connected to the phone, the charging will start automatically.
Turn on the screen and swipe up to check the battery level on your Fire-Boltt Smart Watch.
How Long Do Smartwatch Batteries Last? Most smartwatches are designed to last for at least a day. This usually means 12-48 hours of use, which is sufficient provided you are willing to charge your watch at night. If you want something that can be worn all the time, some smartwatches do offer longer battery lives.
You're more than likely going to need a wear app, but it should be very easy.
On the wearable, make a WearableListenerService. Have the phone app send a message (using the Message APi). This will start the WearableListenerService on the watch. Have the watch get it's battery information and send it back to the phone using another message.
