Kepler Watch

A complete, ready-to-wear watch; no donor watch needed. The familiar shape of a popular digital watch, rebuilt from the ground up around a crisp OLED display and a low-power Bluetooth radio.

It looks like the classic you know, but behind the display now sits a small watch operating system that you navigate with the buttons. Three buttons. One coin cell. No subscription.

On the watch – no phone needed

• Time and date, 12/24-hour; the time can also be set right on the watch, no phone needed
• Stopwatch, accurate to a hundredth of a second
• Countdown timer that flashes the whole screen when it finishes
• Flashlight with adjustable brightness: the whole display lights up white
• Silent alarm with a flashing screen: set the time in the app, switch it on or off on the watch (no buzz, no vibration)
• Info screen: the temperature the watch measures itself, the battery level and the next alarm at a glance

With your phone – over Bluetooth

• Mirrors your notifications: email, text, voicemail and missed calls; incoming calls and messages appear full-screen with the name
• Scroll through your last five notifications on your wrist and dismiss them right on the watch
• A media remote for the music on your phone: play/pause, next and previous track
• Ring your phone and find it again; the other way round, the app can flash the watch
• Image screen: a photo of your own on the watch, cropped in the app and converted for the black-and-white display
• Bluetooth screen: see the link and switch the radio on or off
• Screens your way: show or hide every screen but the clock in the app and set their order
• Keeps time, time zone, daylight saving and weather in sync automatically

The essentials

• User-replaceable CR2016 coin cell: no charging, no cable
• No subscription, no cloud account; the watch is yours
• Fully assembled, case included; nothing to source separately
• Hand-built in small batches, shipped from Munich

Other case colours are available on request by email.

The phone features run through a free, open-source Android app. An iPhone app is not available yet.
