Frequently Asked Questions

No, you are not locked in. Kairos supports Android, iOS, and Windows Phone devices, so you can switch anytime.

If the apps from your smartphone support Bluetooth push notifications, then Kairos will be able to display them. If the apps do not support Bluetooth push notifications, then we will need to work with the developers to implement push notifications.

Kairos does not support Android Wear. At this stage, Android Wear draws too much battery power; however, actionable notifications through the Android platform will be implemented in summer 2015.

The Hybrid Smart Watch has a functioning microphone, but it does not support making phone calls from the watch. The watch does not have a speaker, so it wouldn’t be much of a conversation!

(NOTE: so, what is it for?)
The microphone is built for future use of behavioral analysis, such us sleep analysis or other types of functionality that is still under research.

You will not be able to write out custom messages through the watch because including a tiny keyboard on such a small display is not user-friendly. However, you can send out pre-set text messages.

(NOTE: can this really be done? We did not manage how to do it)
This functionality will be included in near future firmware updates and only supported by android phones.

The watch winder can simultaneously wind the mechanical movement and charge the smart watch battery, but it will not be able to charge the T-Band.

The lug ends of the Hybrid Mechanical Smart Watch are 22mm and can be switched out very easily. You can do it yourself!

An automatic watch relies on the motion of your arm to wind itself, meaning you won’t need to manually wind up the watch as long as you move. However, it does not generate enough energy to power the display or chipset.

The GPS unit is only present on the T-Band ND version due to space restraints on the Hybrid Mechanical Smart Watch and the T-Band HD and OD models. The GPS unit on your smartphone can be pushed out to the watch.

Yes! However, we will work on this after the current generation of Hybrid Mechanical Smart Watches are completed.

At this stage there are no custom watch faces since the watch face is not digital.

The Dot-Matrix version of the Hybrid Mechanical Smart Watch and T-Band OD will support English, French, German, Spanish, Russian, Arabic, Simplified and Traditional Chinese, Korean, and Japanese. The ICON version of the watch and the T-Band HD will support English only.

In general, if:

a. Your watch lug ends are between 18 and 24mm, and

b. You can switch your watchband with other bands, regardless of manufacturer, then yes, the T-Band should be able to work with your watch. The T-Band is 22mm but can be fitted onto lug ends between 18 and 24mm by using an adapter.


In general, if your watchbands are fixed onto your watch or are custom made to fit to your watch brand only, then no, the T-Band will not fit with your watch. We will need to work with your brand directly to create a T-Band that fits.
