$100 GLIGO E-Ink Smartwatch Promises “2-Year Battery Life” (Crowdfunding)

Orange Pi Development Boards

Wearables are useful little devices, but many of them suffer from short battery life, and in my case at least, I forget to charge mine from time to time. So when I saw GLIGO E-Ink smartwatch promising 2-year battery life on a charge, it caught my eyes.

But then looking into the details, it looks like battery life is really 6 months unless you don’t plan on using the display:

We adopted an energy-efficient dual-core design:the quartz core has a battery life of up to two years, e-ink screen has a battery life of up to 180 days.

Six months is not that bad either, so let’s still have a look.

GLIGO E-Ink Smartwatch

GLIGO E-Ink smartwatch specifications:

  • MCU – Unamed Arm Cortex M3 microcontroller with 128KB memory
  • Display – E-ink segmented display
  • Japanese Watch Movement
  • Connectivity – Bluetooth 4.2 LE
  • Sensors – Green light heart rate sensor (HRM), 3D G-sensor, 3-axis accelerometer
  • Misc – 15,000 rpm vibrator
  • Battery – 100 mAh charged with magnetic charging
  • Dimensions – 41mm ∅ x 12 mm thickness (361 stainless steel + tempered glass)
  • Weight – 58 grams
  • Water Resistance – 3 ATM (up to 30 meters deep)

The battery situation is a little odd, but as far as I can understand, the quartz is maintained by a non-rechargeable cell coin battery (and typically lasts 2-year), while a separate rechargeable battery is used for the e-ink display and related electronics and can last up to 6 months on a charge. The exact duration will depend on Bluetooth connectivity, notification frequency, and heart rate monitor usage. So even if the rechargeable battery is depleted, you could still use the watch without E-Ink display, by just reading the time using the watch’s hands.

The face comes with straps made of full leather or stainless steel mesh. it can perform all talks found in fitness trackers like step counting, heart rate monitoring,  sleep monitoring, setup alarms (with vibrator) and reminders, as well as handle notifications from Android or iOS smartphones thanks to GliGo watch app.

The watch launched in Indiegogo and with 16 days to go, close to 2,600 backers pledge around $240,000, well beyond the funding target. But there are still many $99 early bird rewards with either steel mesh or leather strap. The watch come with a charger, and since $100K and $200K stretch goals have been met a button cell battery and Apple USB cable will also be included. Shipping is free worldwide, and you should expect your reward in September 2018 if everything goes accordingly to plan.

I’m getting older, and I’m seeing 2 needs that aren’t being met for me and my peers (I blame it on engineers and marketers being too young, trendy, sporty ^^).

Both are for stylish devices to be worn while at work or on the town, w/o looking like a dork or a misplaced athlete:
1- a simple smartwatch that simply forwards high-priority alerts, for parents’ kid emergencies and high-availability professionals, so that you ALWAYS get that important message (pick up the kid, call back your boss) even if your phone is at the bottom of a bag, you’re in a noisy bar… Basically just “pick up your phone !”)
2- a ‘”social-only” smartwatch (no sports stuff, so smaller and more stylish) especially for service/sales workers that can’t use their phone during working hours but don’t want to lose touch with all their “friends”. Allows you to discreetly message.

An e-ink screen seems like a good fit for both.

They claim 30 m water resistance with an IP65 classification. It’s completely wrong and misleading. The IP65 classification does not allow any submersion. It only guarantees that low pressure water jets have no harmful effects at a distance of 3 m!

It is not very reassuring to commit money on it…

It’s an IP68 worthy seal but the materials aren’t anti-cursive to withstand hours of exposure to sea water and chlorinated water as those might damage the strap or the finish so they didn’t certify over IP65. IMHO unless they advertise as a diving / sports watch, it’s not an issue.

and probably for 50$ in a flash sale on 11.11

If I was designing this then:

a) would ditch the dual-battery thing and just have a single replaceable lithium battery powering everything. Non-rechargable batteries have about double the energy density of rechargables, and for the timescales involved, just replacing a battery is reasonable

b) Digital LCD clock display instead of analogue, again about twice as energy efficient.

Can u believe it?
if this is true, the campaign is fraudolent. wish i didn’t participate
