Say I am wearing my Pebble Time and I decide to switch to my new Core2Duo.
I open the new Pebble app and disconnect the Time.
I turn on my Core2Duo. The watch displays the time as 12:00.
My older Pebbles store the time and remember, even after being turned off. Is the behavior of my Core2Duo correct? Is there a setting I am missing somewhere?
Thanks in advance to any help you can provide!
There’s no persistent RTC on the C2D, I think it’s the same on all the newer watches
The Pebble 2 Duo will not keep time if you shut it down. You will need to reconnect it to your phone to get the latest time. Thanks!
Would vote for this as something to add for future models, not a big deal with the epic battery life but could see a situation when out camping or something where this could be an annoyance 
. Say your phones is dead and you need to restart the pebble ect ect.
Hi folks
I may be mistaking, but I think that all watches OGs and new ones are implemented with RTC on SoC. Than keeping correct time until the battery goes all bunkers is a thing of firmware implementation, I recon.
Would love to have the option to manually setup time if they not connected to phone and battery goes flat anyway.
@eric some thoughts on this matter ?
My personal option is that Pebble represents 21st century Casio watches. And they first and foremost watch so been able to set time manually should be given.
Cheers
No, there is no RTC on P2D/PT2/PR2.
Re option to set time on the watch. Totally agree! We’d welcome a PR to PebbleOS that would add this functionality!
I appreciate the responses. I started thinking I may be old, wanting my watch to keep time, LOL. I mean I am definitely old.
Time marches on, friends.
That is a very odd decision, not to have an RTC on a device that is very much watch shaped. Was this a deliberate choice? Seems more like an oversight.
Given that, there definitely should[TM] be an option to set the current time without the requirement for a functioning phone.
An obvious choice would be a GPS/Galileo receiver, of course, but I am aware that that comes with space and energy constraints.
How about old style “radio controlled“ watches that get their time from terrestrial time signals. Is that still a thing?
yes, definitely an oversight! We missed it in the original P2D design and that oversight was carried over to the Sifli-based design as well.
we’d appreciate a PR for this if anyone wants to contribute it!
@eric, can you elaborate on the PT2 missing an RTC? I’m not familiar with the SF32LB52x family, but looking at the manual for the SF32LB52x, there does appear to be an RTC for the SOC? Or does the specific variant on the PT2 (SF32LB52JUD6) omit this peripheral?
I haven’t checked, but it probably doesn’t preserve time across the hardware reset.
