Needs improvement

You can only connect it to one device, if you try to connect to another device it will reset the previous one. Adjusting the home time and world time is cumbersome. It only works when you leave the app open in the background, but doing so drains the phone’s battery quickly. Once it is added to the app, the phone will not adjust via radiowave.

Do this before pairing the watch

For anyone with the model OCW-T200 do this before pairing the watch to your phone.

Pull out the crown two clicks. Hold the button for ~10 seconds until the seconds hand goes to C. Release the button, let the second hand return to the previous position and then push the crown in. This procedure unpairs the watch from the phone. It may have been paired with another phone prior which is causing issues. This information is not in the instruction manual. Once I performed this procedure the App works flawlessly.

Great app

Works exactly as it’s supposed to. No idea what the bad review was about but the phone isn’t supposed to get radio waves to adjust. Only the watch does and as soon as you’re not using the app it can receive radio signals to update. The way the watch updates time with the app is through Bluetooth and it does a very good job at that. Love this watch and the app.
