2am Raspberry Pi - Citizen PMD56-2952 Automated Atomic Time Sync

[@BalafreX]

Is there any option to switch AUTOMATIC synchronization to MANUAL ? Just to avoid unnecessary searching for signal.

[@johnnyknoxville5003]

What does actually happen at 2' and 4' oclock when the watch wants to sync? And lets pretend the european scenario: No tower signal, no app signal, no RP Does the watch stop in the RX psition for some time and then shows NO and continues or does it spin like crazy? Or does it make some odd noises? Guess i actually just want to know if its still usable at those certain points in time. Cheers and very helpful series of vids, thank you

Not op but I own ton of wave ceptor/ radio controlled watches. They just go to RX position (or any other receiving indicator) once every hours within their designed RX hours, try and then go back to normal operation. If you don't have any tower near you, they still are normal quartz or solar quart watches - which are very reliable. They syncs at night, so after a while, I don't care much about this feature.

Hello Can you please make a tutorial on how to do this with the raspberry ? I'm planning to get this wonderful watch Thanks

If you google: "txtempus" you'll find the project and instructions on how to make it. My friend helped me build this one (and solder it) - it does take a bit of work but it's possible to do. The channel is over now unfortunately, no more videos will be made on here.

@@simonthewatchguy6073 thank you. I really liked your review on the PMD56 🍻

I just synk mine with the app

Omg you made it happen... #baws

serious question... what's the point? why go through all this trouble when there's ClockWave ??

[@simonthewatchguy6073]

Because the watch automatically looks for a signal during the night. Clock wave can’t be set to autorun at those times, therefore this project was worth doing i think

@@simonthewatchguy6073 -- okay I guess I see your point currently I have a seiko automatic every morning I wind it once a week or so I check the official govt time website and manually sync it up for my purposes, I don't think its too onerous to run the app on the ph and press the update button on the watch once a week or maybe even once a month to keep the watch telling the right time maybe someday I'll look into going the raspberry pi route (perhaps one day someone will even make a special built device to do it!) :) thx again! have a great day :)

@@SDsc0rch I ended up selling this watch so maybe it was too much effort in the end! Cheers, have a great day too!

[@stinkystealthysloth]

That looks like a lot of fun but I'm sure it gets old fast haha

[@johanbertilsson2213]

My Casio Waveceptor also has the markings RC when it takes the signal, and OK when it has syncronisides with the atomic clock in Germany.

[@simonthewatchguy6073]

Nice, I guess Casio must stick with RC. Atomic watches are great!
