The new Telstar Online Time Sync collection offers synchronisation to the Atomic Clock, and each watch in the collection features the ability to improve its accuracy over time through self-calibration.

 

These innovative timepieces utilise a photovoltaic cell embedded in the face of the watch to communicate with a PC or Smartphone App.

 

In order to sync the time, the user just holds the watch up to his PC or smartphone screen, and initiates calibration mode on both the watch and the PC app. The photovoltaic cell "reads" a signal which is sent by the PC via a series of flashing lights, and sets the time and date to be in sync with that of the PC (which is in turn synchronised over the internet to the atomic clock).

 

Each time the watch is synchronized, a microchip measures the degree to which the watch has deviated from atomic time during the period since the last sync.  It then calibrates the movement to allow for environmental factors such as temperature which impact the normal timekeeping accuracy of a quartz watch.

 

This self-calibration literally slows down or speeds up the watch as needed to adjust for the temperatures experienced during normal wear – with the result that the watch becomes more and more accurate each time it is synchronised.

PC APP

 

In order to synchronise your Online Time Sync watch with a PC running Windows XP/Vista/7/8, download the app here.

 

Right-click the Zipped folder and unzip all files to a location on your hard drive. For ease of access to the app, you can then right-click the executable file "Time Calibrator V5.0.exe" and select "Send To Desktop (Create Shortcut)". You can then move this shortcut to a location of your choosing. Note that this step is optional.

 

To run the Time Calibrator app, open Time Calibrator V5.0 either from the unzipped folder or via the desktop shortcut mentioned above. The following screen will appear while the app automatically tries to connect to an Internet time server to ascertain the correct current time:

 

 

 

If a network connection is active, the app will automatically update to current internet time based on your selected Time Zone (via the app settings – default GMT).

This current time will then display within the app as follows:

 

 

 

To calibrate this current time to your watch, put the watch into Calibration Mode as follows:

 

Next, click "Calibrate" on the PC app.

 

Hold the watch up to the PC screen, with the watch face directly over the "Calibration Zone" as follows:

 

 

 

The Calibration Zone on the app will flash a number of times.

 

For Digital version M7000 xxx, the watch will beep to indicate successful calibration. The watch Primary Timezone should now be ticking in perfect time with the app.

 

For Analogue version M7003 xxx, the watch will not beep, however after the app finishes flashing the seconds hand will revert to normal timekeeping.  If calibration has completed successfully, the watch hands will be in perfect sync with the app. If not, simply try the same procedure again (remembering to set the watch to Calibration Mode first).

 

For optimal performance, it is suggested that you calibrate your watch 3-4 times a year.
