You may have some questions...
We tried to answer some of those questions that may pop in your curious head. For anything else, you can always shoot us an email.
1. General
What does that mean? Well, you can shower with it.
The usb port looks exposed, but don't worry, water won't get through it.
The port, upon drying can become usable again.
In addition to that, we have also conducted durability tests such as salt, sweat, scratch, grind, and more.
We made our own automatic robot testing jig to put the theory to test.
Internal LiPo Battery’s capacity:
≈ 1200 mAh
Realtime clock’s backup cell’s capacity:
(Only kicks
in if the the LiPo battery is drained, to keep the RTC
ticking)
≈ 7.5 mAh
Power consumption when not doing anything:
≈ 0.7-0.9 uA
Power consumption when checking time & date:
≈ 27-31 mA
Battery’s life:
Battery Capacity (mAh)
Consumption (mAh) * (1 - discharge safety)
e.g. Battery’s life:
1000 mAh (it’s never exact as written in data-sheet)
28 mAh (let’s say in avg.) * (1 - 20%)
≈
~ 44 hrs
(approximately 2 days,
if the watch stays on continuously)
2. Maintenance
Note: We will already set the time, according to your timezone, before shipping and hopefully you won't need to set them very often.
- Waking Up the Watch: Press the button once to wake up the watch. Upon waking up, the watch will first display the current time.
- Entering Reset Mode:
To make adjustments to the watch settings, perform a long press and
hold the button for approximately 1.5 seconds. This will take you to the
RESET mode. The first thing you can reset is the hour, meaning you are
in "reset hour" mode.
- Adjusting the Hour:
- Once in RESET mode, the display will show “hr” (for few seconds), indicating that you can change the HOUR value (Image 1).
- Use short presses to increase the hour value. Note: The hour value will cycle back to 0 after reaching 23.
- After you land on the desired hour value, confirm it by holding the button for approximately 1 second.
- This will now take you to the “reset minute” mode. (Image 2)
- Adjusting the Minute
- Following the hour adjustment, the display will show “nin”. Due to the limitations of 7-segment displays, "min" for minutes is represented as “nin”.
- Use short presses to increase the minute value (just like the previous step).
- Once you've changed the desired minute value, confirm your selection with a long press by approximately pressing the button for 1 sec.
- This will now take you the "reset seconds" mode (Image 3).
- Repeat the above steps to change the SECONDS, then DATE, MONTH, and YEAR values (Image 4, 5, 6).
- Note: If you wish to skip adjusting a particular component (e.g. the seconds, the year etc.), simply perform a long press (approx. 1 sec) to move on to the next component.
- Adjusting the Hour:
- Exiting Reset Mode After setting the YEAR value, the watch will automatically exit the RESET mode, and your adjustments will be saved. Note: If you wish to leave the RESET mode in the middle, just press long enough (2.5 sec) and release.
Notes :
- The "Year" value rolls over after approaching 2100. This decision was made to make it easier on the fingers while manually resetting components with the button.
- Always make sure that you have set the correct values for each component before exiting the RESET mode.
Image 1
HOUR (hr): Now you can change the hour
Image 2
MINUTE (Shown as nin - as it is hard to represent in 7 segment): Now you can change the minute.
Image 3
SECOND (sec) : Now you can change the seconds.
Image 4
DATE (date): Now you can change the date.
Image 5
MONTH (Shown as non - as it is hard to represent in 7 segment): Now you change the month.
Image 6
YEAR (year ): Now you can change the year.
Typically, inexpensive digital watches utilize a single button for programming the date and time (as mentioned earlier). This process often involves multiple steps, requiring different types of button presses and nested interactions. It can be cumbersome and therefore easily forgotten or difficult to operate without consulting the instruction manual. Moreover, who typically keeps the provided instruction manual handy at all times!
So, we decided to use a computer for resetting/programming the time and we call it, “time syncing”. Setting time from here is super simple.
You can also set the duration for how long the display stays on.
Now, if you are ready to reset time and date now click the button and follow the instructions, step by step.
Important note before proceeding:
If you are on Windows, please download and install the driver first. Also, Linux (Tested on Debian derivatives) is not supported currently, unfortunately because of some kernel driver issues for our chip (we noticed it too late; we will fix that in next version!)
Sorry, but your browser does not support web-serial which is used to sync time. Please use Google Chrome or Microsoft Edge.
3. Accessories
Also, since it is so simple to remove the belt, you can experiment yourself as well. Currently, we are talking to a friend and planning to design an Albert Chain/Necklace for it. We will keep you posted about its status.
