Pre-Production Samples + Video

Posted by Pebble Technology (Creator)

Things are moving fast in Pebble land. We're progressing rapidly through our Engineering Verification test stages. We've been spending a lot of time in Asia working with our manufacturing team and the various vendor factories that are supplying parts for Pebble. Two weeks ago, we did a sample build of Pebble with the full assembly line. The output of that sample build was a few of the first assembly line manufactured Pebbles!


Pebble is not in mass production yet. These sample Pebbles are from an early pre-production test build. We only turned the assembly line on for one day to test the process.

One of the first Pebbles off the test assembly line. Check out the video above for a closer look!

Environmental Testing

Now that we have more complete sample Pebbles to work with, we're beginning environmental testing. This means putting Pebble through its paces and seeing how the hardware holds up in a variety of everyday (and not so everyday) conditions. Here are just a few of the tests that Pebble is undergoing:

- salt water test
- water proofing test
- UV aging test 
- Drop test  
- Twist test with bands 
- Lens impact test 
- abrasion test 
- button reliability test 
- tension pull test with wrist straps installed 

Antenna testing

We can confirm that the issue we were having with the antenna (Update 18) has been conquered! The latest samples have vastly improved range and meet all of our requirements. Originally, our design included a chip antenna (similar to this), a simple antenna that's easy to use. But after testing back in August showed degradation of the signal inside a test Pebble, we redesigned the radio-frequency (RF) path. We switched to a custom-built antenna solution that uses metal traces positioned to be higher above the bottom of the watch, allowing the RF signal to be clear of water-filled cylinder that is a human wrist.

2-3 test builds remaining before mass production

Before we get into mass production (ie manufacturing all 85,000 Pebbles), we have several more test builds to complete. A test build is when we get the whole assembly line into place and manufacture/assemble a batch (normally around 50-300) of Pebbles. These test builds give us the chance to test the end-to-end manufacturing process, catching problems, testing new solutions and eliminating bugs. These are our major opportunities to revise and fix any problems with the design or manufacturing process, so we're being extremely diligent and careful. 

Testing different variations of batteries, vibrating motors and backlight modules

For example, we have several different vendors lined up to provide components for Pebble like the vibrating motor, battery and flexible printed circuit (FPC). In these test builds, we are qualifying each vendor's components and making sure that they are suitable for us to use. Having multiple vendors available for high risk components allows us to switch one component out for another in mass production if issues or delays arise with that specific part.

Color Pebbles

Check out the video to see a few samples of the color Pebbles. We aren't happy with the precise colors, so we're still working on tweaking the plastics. As soon as we're happy with the colors, we'll post high resolution photos in a future update.

T-shirts giveaway!

Here's your chance to get one of our cool 'Meet Pebble' t-shirts that I was wearing in the video. All you have to do is tell us what you're planning on doing with your Pebble ("Checking email while paragliding" or "Skipping music tracks from the bath tub" or even "Writing an app to control the sun..."). Post your answer in the comments section below. We'll choose our 10 favourite answers and give the responder a red or grey a 'meet pebble' t-shirt (their choice).

Thanks again for backing us, Pebblers!

      I am really looking forward to using pebble for teleportation. It will also be great for zapping out street lamps like in the first harry potter movie!

      Skipping tracks whilst working, neurosurgery keeps your hands full, no time to pull out an iPhone. Will improve usage of iPhone considerably, until ithoughtPhone is released in 2023 or so I thought.

      I'm eager to wrap pebble around my wrist, so definitely going to wait and see. As a backer there is certainly some impatience involved though...

      I will connect most of the electronics in my home to a microcontroller. I will then write an app to control that microcontroller from my pebble watch. Forgot to turn the lights or heater off? No probs, just gotta push a button on my watch. Feeling to paranoia? Add motion sensors to my room that would alert me through my watch to alert me of any intruders.

      I admit I would like to have one in my hands, that being said I would rather wait & have a quality product. Like some people I bought it as a gift for a November birthday, if I don't get it in time it will become a Christmas gift. If it still isn't here by then well there's Valentines Day, etc. Thanks guys! No matter what day it is my man will love it!

      I will pass my Pebble thru the left sleeve of my "meet pebble t-shirt" every day on our way out to new adventures of awesomeness! (Better send me a few so I don't have to do laundry so much!)

    20. Richie on

      I'm sure that the pebble in black is so cool, that it will become most powderfull gadget of the Man in Black, just like the "sun swallowing black hole app". Neuralizer-App!

    21. Rasmus Ahlberg on

      Looking forward to using my FlatTireRunningLate App (complete with updated ETA) on my Pebble when bad luck strikes on my daily fixie commute to work. Will shave off valuable minutes not having to pull the phone out and compose a message before replacing the tube.

      I can't wait to wear my Pebble 24/7 and check messages right on my wrist and control my tunes and .... the opportunities just seem endless.

    25. Kubocentral on

      Use it as a "cool" watch... to tell time.

    26. Jeffrey Wong on

      Thanks for the updates!!! And the black Pebble looks awesome!! I am going to change my color choice to one orange and one black. By the way, you update also help me to satisfy my girlfriend for awhile as she keeps asking me where is her Pebble...LOL

      As plan, I am going to use my Pebble to remote trigger my DSLR shutter, aperture or other photography accessories connected. Hopefully the SDK can provide me a way to achieve that.

      Other than that, I definitely will wear my Pebble to make my friends jealous. LOL

      I'm planning to use my Pebble to enhance my "street cred" with a younger generation. Although it'll work on the high school and college age kids I coach, I probably won't be telling my wife that it's anything but a watch because that would enhance my "geek cred" with her.

Thank you pebble developer team.

    35. Kieth H. Vey on

      I'll be using my Pebble as another way to procrastinate from tasks I'm supposed to be tending too. Just like any good gadget should be able to do. =)

    36. rileyjshaw on

      I'll use my Pebble to track and improve my sleep patterns and log my workout stats using the accelerometer. Need to get my hands on the SDK first, though :)
      I'll also use it (if possible) to push triggers to a webserver that my Raspberry Pi is watching... sleek TV remote on my wrist.
      + I'll share my creations with other Pebblers.

      I'm updating my comment since I was thought we were supposed to post a comment on where we would wear the shirt but my comment still stands which says I will have the opportunity to let people know about the Pebble Technology team behind the watch and their ingenuity, trust,faith in their product and people.

      I'll be wearing the Pebble shirt while I'm helping people get rid of pain as a physical therapist . I'll also wear it while I'm working out in the gym in the biggest loser competition and especially while I'm singing in the choir at church or doing a solo. It will give me the opportunity to start a conversation about putting your faith in a project that you believe in . Also it will give me the opportunity to talk about working on goals that you don't give up on and how you can find a way to succeed even when you have to step out of the box to do so. But the most important thing is to have love for people, establish trusting relationships with the goal of helping everyone succeed. It appears that the Pebble Technology Team is all of the above.
