Plastic Samples, iPhone 5 and More!

iOS 6 Update and iPhone 5

Bit of news: Apple released an update to iOS this week. iOS 6 is available for free on all the phones that Pebble supports (iPhone 3GS and up). We've had access to iOS 6 through the iOS Developers program for the last few months, and we've been testing our software with both iOS 5 and 6. The big news in iOS 6 is a new Bluetooth profile called MAP. We've integrated a MAP receiver into Pebble, but we still have a bit more testing to do with the iPhone 5. So far it's working really well! There is no reason Pebble should not work perfectly with iPhone 5.

Samples from our Plastics Factory

I mentioned in Update 17 that we were about to start the injection molding process. Creating molds or 'tools' is hard, literally. The process involves carving a Pebble-shaped cavity out of hard steel blocks and even with our accelerated schedule, it took 6 weeks. We had to make separate tools for each of the pieces of the watch (buttons, case, lens, strap). 

After weeks of work, we ran the first test shots of the mold. It's awesome to see the long, hard work of our industrial designer, tool designers and mechanical team pay off.

This is an important step towards mass production. Steve, our industrial designer, is in Taiwan right now evaluating samples which are literally hot off the presses. We think they look great for first shots, though we've got a bunch of tweaks to make to ensure that all plastic components work and look perfect. The only color we've made so far is black because we can't afford the down-time needed to fully clean the tool. As soon as we have samples in other colors, we will post pictures. 

We will leave color selection open past Sept 30 at (Entries can be submitted past Sept 30 now). We will email all backers before closing color selection.

Tons of buttons!

Steve, our industrial designer, was on-site in Kaohsiung, Taiwan and took a bunch more photos (full album).

Printed Circuit Board (PCB) Progress

In parallel to the plastics work, we've made several revisions of the circuit board. With each revision we eliminate more bugs and improve the design. In response to a problem we had with the antenna, we created 3 different potential designs and then prototyped and tested each sample extensively inside an anechoic chamber. The best design prevailed and we've integrated that solution into our PCB.


We've got the whole team working extremely hard on Pebble, but there is a lot of work left to do.

Software Development

On the software and firmware side, we're in the process of strenuously testing Pebble's ability to receive new updates wirelessly via a smartphone. This means that even after you receive your Pebble, you can update the software on your watch simply by tapping a button on your phone. Our software team is also busy writing the underlying code for Pebble's customizable user interface, as well as the apps, like watchfaces, notifications and more, that run on top of the Pebble operating system. 


Now that our plastic manufacturing process is up and running, we're able to make lots of test units and iron out the kinks in the software, as well as the hardware manufacturing process. We've designed a strenuous test plan that will put Pebble through its paces. Right now (before we go into mass production) each aspect of the design, from water resistance to button presses to battery lifecycle, is being tested. Then when the factory is in full production mode, every single watch will be tested to be in compliance with our quality requirements.


(This section has been reposted on our forums for discussion)

The last update we've published about Pebble's Software Development Kit (SDK) was in June, when we described what the Pebble Android SDK would look like and launched Since then we've been pretty quiet on the subject.

I'd like to take this opportunity to talk about our roadmap towards creating an awesome developer environment on Pebble. At the moment, we're focusing 95% of our software effort on writing the base operating system and features for Pebble, on top of test routines that run in our factory. The sheer amount of work is enough to keep our 5 person software team quite busy. We feel it's important to build a strong foundation that's highly usable for both users as well as developers.

Part of that foundation is the ability for Pebble to easily run third-party apps. We've built this into the core architecture of our OS. The following is our plan to enable developers to create software that works with Pebble. Please keep in mind that this is a roadmap, we'll be releasing more info over time.

  • Android SDK: It's easy to integrate new or existing Android apps with Pebble. Our SDK uses intent messaging, allowing other apps to push messages, notifications or even sports data to Pebble. As soon as Pebble ships, developers will be able to use the API calls described on to integrate their apps with Pebble
  • Notification API: Web developers will be able to add Pebble integration to their webapps as well. We're building an OAuth 2.0-enabled endpoint linked to the Pebble Account system. After asking Pebble users to authenticate, Notification API-enabled webapps will be able to push notifications, alerts and other data directly to a Pebble. The API takes care of all the communication between the web, phone and Pebble.
  • Watchface SDK: All the tools needed to create your own custom watchface for Pebble. This is our first experiment with 3rd party code running directly on Pebble's microcontroller. Developer tools and documentation are the most difficult part of this SDK stage.
  • iOS SDK: Things are a bit more complex on iOS. There is no simple method for doing interprocess communication between apps. We're pursuing a few different options. We're confident that the solutions we're building will work. 
  • Expanded Native SDK: At this stage we'll expand the featureset of the native development platform introduced with the Watchface SDK. Think games, sleep trackers, remote controls and other more complex apps.

Thanks for bearing with me through this long update. If you have any questions, please do not hesitate to email Thanks again for backing Pebble!

      As much as I'd like a watch soon, it matters a whole lot more than the product is of great quality, especially for us backers who donated money for an unfinished product.

      Please take your time with refining the tooling. The first close-up shot in this update reveals that there's still a bit of refinement left to have the watch looking polished.

      Thanks again for the updates, it's amazing how great these updates are considering the amount of work to be done.

      As Vaughan has pointed out, the Pebble has always been glossy. Watch the kickstarter video again. The prototype and all the renders had a glossy surface.

    3. Steven on September 24, 2012

      How strong is the plastic watch face? As in is it scratch resistant? Is it such that we have to put a screen protector on?

      please, dont glossy surface!

    5. Vaughan Stedman on September 24, 2012


      Really? What did you expect?

      For one, it is a plastic watch. Also all the renders of the watches have clearly been glossy...

    6. dtdw on September 23, 2012

      please no. dont want glossy surface ! .. its like wearing a plastic watch. if it's matte, at least its wearable in semi-pro occations and not being laughed at wearing a plastic watch.

      Great update & I agree that I prefer quality over speedy shipping.
      Having said that; you should give us a shipping update as well. Even a statement like ' will not ship before XYZ date' would be a step forward.

      will there be better photos of all four versions of pebble before color selection ends? So far, we've only seen glossy black pebbles on photos. I'm really wondering how it's going to look in color. I don't expect the current computer images to be a good representation of the real thing, making it a difficult basis for color selection.

    10. Guillaume Perras on September 23, 2012

      Can we have higher resolution images?

      Wow, looks really cheap these plastic! Hope this might still improve. Better should have waited with ordering this…

I only use about 800x600 on my browser most of the time and I even expanded it to 1024x768 and I cant stand scrolling left and right, back and forth to read shit.

      Asking for an estimated ship date is hardly whining. I too want team pebble to ship when ready and not a day before. But, even the most avid supporters have a limit, for example, if you still don't have an estimated ship date by the end of Oct., would you still be OK with that? How about Nov., Dec.? I know a lot of folks immediate thought is, "it won't take that long", but that's not the point, the point is everyone has a limit. And I'm not talking about ship dates, I'm talking about an estimated timeline for shipping. I doubt anyone wants a less than awesome product and I think the vast majority are more than willing to wait, they just want an idea of when that will be. I'm thrilled with the updates and team pebble's communication on other social media. Ultimately Pebble will make the best decision on when and how to communicate shipping, it's their business and they want it to succeed as much as us pebblers want them to succeed. Posts to these updates serve as a means for backers to communicate to team pebble and people asking for a ship date is valuable feedback. Right now I'm guessing the people asking for an estimated ship date verse those that are not is about 50/50, in a month, if a ship date is not provide, I'm sure more people will want to know.

      Thank you for such a detailed update. It is great to be informed of all of the pre-production planning, testing, software development and revisions. It makes me feel that my money has been well spent as a Kickstarter backer when I can see all of the hard work that is going to bring the Pebble to production. It also is good to know that you are more concerned with bringing a fully baked product to market rather than rushing it to production and having to conduct damage control after-the-fact. Keep up the good work and don't worry about hurrying. It's better to get it right the first time.

    24. Jason Scott on September 23, 2012

      As I don't define my identity by what accessories I have, and you guys are obviously working hard to make a really nice thing and bring together a great product, please feel free to never give a shipping date and let the whiners just get the box in the mail when it comes.

      I've read through all the updates and I don't really see much info about the golf GPS feature except the maps will be provided by FreeCaddie. Do we have to buy a FreeCaddie app on iOS? Can anyone recall anything else specific about the golf GPS feature?

      Also, I've been thinking about a 22mm NATO strap for it and I recall Eric mentioned seeing a picture in the comments after Update 3. I can't seem to find the post. Does anyone recall seeing the Pebble on a NATO strap pic in the comments?

      Thanks all!

      Still on Gingerbread due to the terrible Ice Cream Sandwich update Samsung and Sprint released.
      Hopefully Pebble will work well with this phone. Still concerned with using my Bluetooth Stereo headset and pebble at the same time. Hope there are no conflicts.

    33. Brett Hamilton on September 22, 2012

      First, great update. I'm tremendously encouraged that you've already got your tooling made.

      Second, don't listen to whoever was encouraging you to just push it out the door quickly and fix the software later in a v1.1 update. That's a terrible approach, and most people I talk to are tired of paying to be beta testers.

    35. Arnold A Sitorus on September 22, 2012

      About the cradle that charging the Pebble.
      Could it have a female micro USB port instead direct cable or even better is they have both?
      So we can use any common micro USB charger when traveling and to avoid having to replace/repurchase another charging cradle when the cable is broken?
      I know there has to be a special connector to charge the Pebble for waterproofing but I'm talking about the connection between the cradle and the power source.

    36. Travis Tidmore on September 22, 2012

      I agree with the above comment on ship dates vs updates. I would much rather keep getting he detailed updates so we can see the progress over being constantly told a mfg date that keeps getting pushed back.

      I know you guys are working your backsides to a pulp on this project. You're absolutely fabulous about keeping us updated. Thanks! The release of iOS6 was expected and the way you're handling it is absolutely professional and indicative of your commitment to quality over expedience. Stay on track and finish what promises to be a great product. The "instant gratification" folks will complain but the majority of us who want a quality product that works will wait patiently while you guys do the "right" things. Do this one "right" and the next 10 or 15 products you bring to the public will have long lines 10 deep to purchase. I remain a devoted Apple addict (20+ years!) precisely because that's exactly what they do. They send us innovative and brilliant, well designed, beautifully manufactured products that work that they stand behind. That formula ALWAYS works. Cheers, KB

      x5 for the China stamp removal, also what would be sick since it looks like it might be possible, is to make the main housing out of aluminum, more expensive but it would be worth it, maybe later on after the initial backers receive theirs

      @Ryan, actually you're not an investor. At all. You donated to a project you believe in at a level that should get you a preorder. Investors expect things like regular updates, inside information, and guarantees. FYI, you have exactly 0 of those.

      This will of course come through because this is an established, competent company, but please don't consider yourself an "investor" in anything on Kickstarter.

      Ryan Hildebrant on September 22, 2012

      Looking good. I for one am glad you guys are taking the time to make sure every detail is perfect. I think it is also fantastic that you are working out all kinks in the SDKs getting developers to put support for the Pebble into their apps will really drive it. I can't wait to get my Pebble, but I also can't wait to see what 3rd party developers come up with.

      I love that you guys are so thorough in your updates, but I would agree we should get occasional updates on the timetable. We're all investors in your product, we all believe in it. You would not be facing a huge backlash. I think that most here would be very receptive to something like "We can't make a solid estimate for shipping yet, but we anticipate shipping before x."

      Keep up the awesome work!
