Very happy

I live in a concrete hi-rise in busy Downtown Vancouver B.C. so I was not surprised when I couldn’t sync my new Citizen ‘’radio controlled’’ watch with the distant radio tower in the U.S..

Fortunately I was aware of the software solutions so it wasn’t a dealbreaker for my watch purchase.

This software was simple to use with my iPad and after about 10 minutes the watch synchronized perfectly. It was very satisfying to see the hands automatically move to the exact time. Just be sure to carefully follow the instructions from Citizen as well as from the software company.

Perfectly works

Works great, I was having trouble syncing my GW-5000u in LA County. After installing the app it worked on the first try. I’m impressed by the app. Good app, try it out. Worth every penny.

Worked flawlessly

This is the only app that immediately showed full signal on the watch and synced it perfectly. It also didn’t have a harsh sound, which made the process more enjoyable. I used it for my Japanese Domestic Market (JDM) watch here in the US. Definitely worth the few dollars.

Excepcional y sin pagos ocultos

Funciona a las mil maravillas con mis radiocontrolados. En mi ciudad a penas llega la de Londres y tiene que darse circunstancias excepcionales. Tengo muchos radiocontrolados esta app funciona Siempre (y tengo muchos) una app que si fuese de pago valdría hasta el último céntimo

It works, but…

I can confirm the app works, it has helped adjust the time on two different watches over a few days. So am happy with that.
On the other hand, it appears to be hard on the battery when left running for 20+ minutes to sync my watches. I’ll have to keep an eye on that in the next few days/weeks to confirm (hence the dropped star).

To calibrate, you tap the 'Transmit' button in the app. Then, set your watch or clock to manual receive time signal mode and place it near your iPhone/iPad's speaker. The app will then transmit the accurate time.

What time signal stations does Clock Wave support?

The app covers five major longwave time signal stations worldwide: WWVB (USA), JJY (Japan), BPC (China), MSF (UK), and DCF77 (Germany). You can manually select stations if your device has specific compatibility needs.

Is Clock Wave free to use?

What if my watch doesn't support a specific station?
