I understand that the watch operating system is open source. However, it seems that the watch will connect to a companion smartphone app. Do you know if the app is a requirement and/or if the app will be open source?
Yeah the mobile app is open source too https://github.com/pebble-dev/mobile-app
It is not clear that this is the app that will be used for the new watches. I imagine it will support the new RePebble watches, but I believe that app was intended for the original Pebble watches.
The thing that makes it so unclear to me is that this is a repo owned by the Rebble team, not the RePebble team. I do not know how much overlap there is between the two teams, but the RePebble team does not have any open source repos that I could find. Any mention of open source software by RePebble (including the OS) are links to repos owned by other teams, which is a little concerning.

IIRC, it has a reflective LCD, not epaper display.
Core 2 Duo
- 1.2" black/white e-paper screen
Core Time 2
- 1.5" 64 color e-paper screen
Am I missing something?
The watch featured a 32-millimetre (1.26 in) 144 × 168 pixel black and white memory LCD using an ultra low-power "transflective LCD"
The problem is that e-paper is a category of displays, and some companies label reflective LCDs as "e-paper". Which is subjective (and I personally heavily disagree with that categorization, cause then LCD clocks and Gameboys have "e-paper" displays, too).
But in the comment I responded to it was said Pebble has "eink" display, which is categorically wrong, as that is a very specific proprietary technology, which is e-paper in traditional sense, like the ones in Kindles.
Where exactly is that quote from? I had a look through the product page(s) and could only find e-paper being mentioned...
Quote is from Wikipedia. You can see it's the case for both models here:
Besides, I own a Pebble Time watch and can tell you, it doesn't perform like a typical e-paper. It has the bad viewing angles of LCD and screen goes blank when power is lost.
That quote is on under features on the article for the original Pebble, right? Might be that the Pebble 2 used a different screen; I can't really find info on that though.
Regarding the Time, I think the product page for the new Time 2 specifically says how the curved screen lens on the Pebble Time wasn't that good.
Edit: Found the quote under the Core 2 Time section
Flat glass lens (less glare and reflections than Pebble Time family curved lens)
From the Verge article:
The first watch that Migicovsky and Core plan to ship is called the Core 2 Duo (not to be confused with the old Intel processor), which Migicovsky says will cost $149 and will ship in July. [...] It has the exact same black-and-white e-paper display as the old Pebble 2 (technically a transflective LCD, if you’re curious)
Your response says, "not epaper" which is categorically wrong. I assume you meant to say "eink"
As I mentioned earlier, whether a screen type is considered e-paper is subjective. And in my opinion, reflective LCD isn't a type of e-paper. You may disagree, but it's not "categorically" wrong.

Oh that seems to be new since the original pebble
I still can't believe that no one else has made a smart watch with physical buttons and low energy use that has surpassed the pebble after all this time. I'm still cautious that this venture will pan out, but honestly there really hasn't been a smart watch released that matches my use case. Sleep tracking makes no sense if I have to charge the watch daily, as I'd probably charge it over night. Media control with screen buttons is awful. Fossil came close with their hybrid smart watch, but the layout of the media controls made no sense and couldn't easily be used without looking at the watch. Just let me check my calendar and texts and skip through ads in podcasts, and last over a week of battery and you will have my money.
Don't love the closed-in ecosystem but Garmin watches with MIP display do almost all you just said.
- Touch screen + also Buttons for 100% touch-free interaction
- Battery life of around 3 to 4 weeks (depending on what you are doing)... more with the Solar models
- Media control is there, but don't really use that
Podcast ad skipping sadly not a thing.
Price might be an issue though. The top end models with all the whistles come at a smartphone flagship price point.
Garmin watches come close?
My Garmin Forerunner 245 Music does all that I'd say
The benefit if the core repebble watches are that they have 1 month of battery life, they're cheaper, and they are open source
I'm still very confused about why we needed PebbleOS for this. It's been like 10 years and no one could come up with any comparable software? They whipped up the hardware design in a few months.
From what I've read from Eric since this relaunch was announced, he just wants a new pebble and so do some of the userbase. This project isn't really intended as a viable, polished product. Rather it's a niche thing made for a Core audience of nerds.
Disclaimer: I'm one of the nerds this is intended for. I instantly pre-ordered a watch because it's a pebble. I7

PebbleOS was awesome, though. Such a well thought out system for end-users, and it already has tons of apps. Developing for it (in C!) is also super easy because it has an amazing SDK.

Torn between this and a bangle.js 2, if I need a smarwatch at all
Having used both, personally I highly preferred the Pebble over the Bangle JS.
Pebble was solid software, good designs and it all just worked simply and did what I needed. I also thought the Pebble Time Round was near perfect in design and execution. I'm not a fan of the geeky look of the normal pebble and bangle watches (or the apple watch look).
The Bangle was fun to dev for, and I love that it exists, but it all felt like a dev project. Not a finished product. Granted it was early on in the project so I'm sure it's in a better place now.
They both have similar capabilities. I say go with whichever you think is going to fit what you need a smartwatch to do.
I want one, but I don't know what I'd do with it. It's hackable, it pairs with a phone/tablet/etc.
I'm just trying to figure out what it can do for me. My lack of imagination annoys me.
I use my autopebble with tasker. Scripted a few things, like find my phone, load my audiobook, messages, etc. Used to have Google Home messages and lights and stuff, but I stopped using smarthome stuff for the most part. Mostly I use it for music control and weather and time though.
I also scripted a weird one that I could enter my feeling level at work throughout the day (1-10) and based on the average at tthe end tasker would play one of three songs when I got in my car at the end of work (only within a time range and if bluetooth was connected to car)
Eh. I prefer the PineTime watch. It was like 25€+shipping and customs and it does everything I need, is fully open-source – it displays weather info, time, date, heart rate (although not very well), and has timer, stopper, etc.
I've pre-ordered the Core Time 2.
Pre-orders are something I never usually do, but given this is essentially just an improved version of an existing product, as opposed to a Kickstarter, I feel more confident. And I can cancel the preorder at any time (plus I'll see reviews of the cheaper model before the Core Time 2 ships).
The price made me wince, though. It's very expensive for the functionality. Technically cheaper than the original watches adjusted for inflation, but that ignores the current-day smartwatch market. Still, I loved the Pebble, so I think it's worth it.
Pre-ordered one immediately. I miss my old Pebble Time Steel so much. Part of me wishes there's one with that design but I'll take what I can get.
Isn't there any way to pre-order without a credit card? I guess I'll have to wait until other payment options are available...
Does this interface with your phone at all? Tried skimming thru their website but the fact it doesn't list Bluetooth in the specs leaves me confused why you'd spend this much money on a quasi-smartwatch that doesn't have that capability.
Yes! The best thing about Pebbles (IMHO) is how they handle notifications. In the specs, they list Nordic nRF52840 BLE chip (BLE stands for Bluetooth Low Energy)

It says they're able to extend the battery life from 7 days to a month due to how efficient the new Bluetooth chips are.
You must have skimmed pretty fast.

It absolutely does, on Android at least. On iOS, given Apple's restrictions, the whole situation is a bit more complicated:

Follow-up question - is this the watch I've been looking for that doesn't spy on me and require a cl of us account to use?
Yes, this combined with gadgetbridge.
A pinetime is also a good alternative. (also with gadgetbridge)
