It's a shame Nav Me doesn't let you do this. I use an (Android only) app called Jarvis which offers some Google Now-style voice-activated features. One of these is "Give me directions to [address]", which runs Google Maps and tells it to navigate to the stated destination. This sorta works, except Maps doesn't actually start navigation until I turn on my phone screen (at which point the TBT directions also pop up in Nav Me). I'm not sure if there's a way around this.
If you use an Android phone, you can try Jarvis. It provides just this function, and has worked fine for me (although I use Timeline-only reminders far more frequently).
I'll put in my usual plug for Jarvis, which (with its Android companion app) implements a number of Google Now features. I use it every day.
I don't use Snowy, since Jarvis provides many similar features integrated with Android (although it's flaky enough that I can't recommend it wholeheartedly). Snowy is platform-agnostic, and actively developed and well-supported by /u/MathewReiss -- worth the few bucks if you like its feature set. If all you need is the ability to quickly set watch reminders, Note To Self works great.
I have a love-hate relationship with my PTS mic, since it works on the first try only a little over half the time (the rest of the time it either didn't transcribe what I said, or I get an error).
I mostly use it to send texts to my wife, but using Jarvis, I also set timeline pin reminders, start music playing, set a phone alarm or timer. I use these features a few times a day, and they make life more fun, even though neither Pebble's VTT nor Jarvis are fully reliable.
You may want to take a look at Jarvis too. It's not under very active development, but it works pretty well for me, and has far better integration into my Android phone.
Jarvis offers a grab-bag of personal assistant features, in the vein of Google Now. Android-only (companion app here).
You can use Jarvis (Android companion app) for this. Set it to a QuickLaunch slot, press and hold on that button, then speak the words "send a text to [contact name] [message text]". E.g., "Send a text to Julia I'm on my way". It does require a confirmatory button press to send, and is not yet fully reliable -- occasionally the companion app fails to kick in, and of course Nuance's voice transcription capacity can frustrate -- but works most of the time for me.
Try Jarvis. I've been able to create phone calendar events by dictation with it, but it doesn't respect the specific calendar I select as default (in the settings of the Android companion app) -- it always creates the event in my phone's default calendar (this may be a bug with the caldav server plugin I use, and not Jarvis itself, though).
If you're an Android user, you should give Jarvis a try -- it does a lot, and it's great when it works, although the backend processing server is flaky, so (even when dictation works fine) it will sometimes sit forever on "please wait - getting response".
For some Google Now type features, you can try Jarvis. It's not under very active development, but I still use it daily, and when it works it's great.
I use Jarvis to set voice reminders and perform some "Google Now" type needs. It's great when it works (about 80% of the time). Other options include Snowy and Note To Self.
I like N2S, but use Jarvis instead, because it offers other Google Now-like dictation features (play music, add event to calendar, set alarm or start timer on phone, etc). Note To Self is more reliable, but Jarvis is more fun.
My guess is that Pebble will eventually implement these features on their watches using Amazon Alexa (the way they are on the upcoming Core), if they're technically able to do so. I have mixed feelings about this since I already use Google tools, but it makes sense for them to use cross-platform methods whenever they can.
For now, I use a third-party tool called Jarvis, which provides more integration with Android features (via its companion app) than any other utility I know. The dev doesn't really have the resources to work on it much these days, and so it's not always reliable, but it's free, and works well enough for me.
Android user here. Some of my thoughts:
Third-party apps:
Current fave watchface: Modern New.
(Running on a Pebble Time.)
You should check out Jarvis (companion app) for some of the "Google Now" voice features you mentioned missing. I have it set to my top QuickLaunch slot, and use it regularly to add reminders and play music. It occasionally gets hung up, but most of the time it works very well (my main issues are with Nuance's voice transcription service).
Nav Me is also a popular Google Navigation app.
I hadn't worn a watch for ten years prior to getting a Pebble Time, so it really cut down on the number of times I'd pull my phone out of my pocket. Of course, any watch would do that, but I love my PTS a ton.
I love trying out different watchfaces, but (as I said in another comment here), discovering them is a PITA. Mostly I hear about them on this subreddit. Some current faces in heavy rotation are TimeStyle, LCARS, Barberry, Obsidian (in square-face mode), and MultiFit.
I have a dozen apps loaded, but only use a few regularly: Jarvis, Alarmist, Sports, Timer, sometimes Nav Me.
If you really want a smartwatch that offers the G-Shock experience, you can find it! See Casio's Smart Outdoor watch series. But you'll pay big money for the privilege.
It's not perfect, but I regularly use Jarvis as a QuickLaunch app to provide a number of Google Now type features.
If you want to create alarms or calendar entries on your Android phone, you could try Jarvis.
FYI, Jarvis can do this, though it uses a companion app to access local Android resources.
I prefer NTS over V2T myself, but I generally use Jarvis (Android only) for this.
