Clock Wave

I live outside the WWVB range, even during the best of times. The northeast usually doesn’t get a good signal. I tried this app, VERY SKEPTICAL of it working with my Citizens Eco Drive watch. I clicked Transmit, turned the volume all the way up on my iPad, and set the watch in manual mode and placed it near the charge port. I waited about 8 minutes, and boom! I got my first OK pointer from the second hand. This app has some serious magic to it.

Acquired my first Casio with “Multi Band 6”, module 3159. I was keen to try to radio sync feature It took a couple tries but the app successfully delivered a signal to the watch. On the Casio I have DST (day light savings) set to Auto, and it correctly determined that DST should be “On” from the app

As said, was about to give up up on the app using my iPhone—just couldn’t get it to work. Now I have tried my biggest iPad with the sound wide open and it works perfectly.

I’ve been using this app for a few years and it is great. The developer is very responsive to my inquiries. The app works and is stable.

My G-Shocks used to sync to atomic time fairly consistently but they’ve had trouble of late. This app saved the day! It doesn’t hurt my ears like I thought it would and works like a charm. Every few days I’ll set the watches out next to my phone and within five minutes they show RCVD. Thanks for the brilliantly simple app!
