I have a 5610 radio square that works as advertised

I also own the big brother to that other lineage watch, the Liw-m700d-1ajf

I spent a couple weeks leaving it in different parts of my home overnight to see if it syncs (it didn't.) I went outside and waved my watch above my head like a spaz to see if I could get it to sync, still nothing. I finally gave up and set the watch manually. disappointed as I was, I also realized that it is a quartz watch and I probably won't have to set it again for like a year.

it's been over a year and it's still accurate up to the second. I even left it at home long enough for it to go into power saving mode at one point. does that mean it is extremely precise? or did it finally start syncing? I don't know, don't care, and you won't either. buy the watch you'll love it
