Ratings and Reviews
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, very useful!
This is a great companion app for your supported Oceanus watch. It makes syncing the time very reliable, enables managing various watch settings and on some phones enables other features like a phone finder and monitoring watch charge levels. The app as it's used for my S5000 could be improved. I like the graph but I would like to view time self adjustment events as a table where I could see distinct Bluetooth and MB6 adjustment events.
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.
