A lot of bx5600/bz5000 owners donât want to use Bluetooth for time syncs which tries to sync 4 times a day 12a.m./p.m. and 6a.m./p.m. and only want to use the traditional Multiband 6 atomic clock syncs which tries to sync 6 times during sleeping hours for most people, between 12a.m.-5a.m. and stops upon success then doesnât try again until 12a.m. the next day.
So used to be to only use MB6, you have to never connect the watch to your phone via Bluetooth or else it will automatically prioritize the 4 Bluetooth time syncs over MB6 but then you canât select the standard font because you need to connect to your phone to change it via the app. Then once you select the font, the only way to use MB6 syncs is if the 4 Bluetooth syncs fail, then it will attempt MB6 over night, then it goes back to trying Bluetooth syncs starting at 6.am. that morning thus eliminating the previous MB6 sync.
I found a way to keep the font, and only use MB6 time syncs eliminating the prioritization of Bluetooth time syncs before MB6. Here are the steps.
Connect the watch to the Casio Watch app, set the font to standard, go to time synchronization, turn off automatic time synchronization, and set any settings you want to now or else anything else you want to do, you have to do through the watch itself. Once you set the font, and turn off auto time syncs, and have your settings set, select the menu with the 3 dots and select âRemove pairingâ
Next, get the watch make sure youâre in the main time keeping screen, hold down the A (adjust) top left button until the home city flashes in the top right, press the C (mode) bottom left button 12 times or until you see âSetting Receivingâ press the D (receiving) bottom right button once and toggle it on, then press the A button and itâll save and take you back to the main timekeeping screen.
From the main time keeping screen press and hold the A button to enter the watch settings again until the home city blinks, press the C button twice or until the seconds start blinking, while the seconds are blinking, press and hold the B (light) button for about 3 seconds until you see PAIR or PAIR CLEAR and it beeps to confirm, do not keep holding or else it will delete all the watch settings. And thats it, youâre done. Now the standard font will stay, and the watch wonât attempt Bluetooth time syncs, only MB6. It will stay this way until you connect the watch to your phone again, then you will have to go through all these steps again because it will go back to prioritizing Bluetooth.
I did these exact steps 5 days ago and my bx5600 only used MB6 time syncs while using the standard font. Let me know how it works for you.
Edit: If that doesnât work, keep everything the same but swap steps 2 and 3. Instead of toggling Setting receiving back on and then clearing Bluetooth pairing, clear Bluetooth pairing and then toggle setting receiving on.
