Many of you surely wonders how to set time and configure the 1st & 2nd Analog Watch ? Okay, let’s go …

*( If your Citizen Ana Digi Temp is slowing down or runs too fast ? check – Adjusting Time ).

*( If you feel that your Citizen Ana Digi Temp incorrectly indicates the Temperature ? be sure and check –  Adjusting Thermometer ).

*( If something else does not work properly – check the Damage Diagram below. This will let you know what’s wrong with your watch and how to remedy it ).

Before setting the Time – make sure that the watch Mode is Normal Time showing.

* Not confuse the Normal Time Mode with the Local Time Mode, which is quite similar, but it has a symbol “L” – which means – Local Time Mark ( picture above ).

1. Push “M”  button to set normal time mode-hour : min : sec

2. A time setting mode is obtained by pushing “S” button for 1 second or longer. Please note that Seconds are now also Displayed Simultaneously and Independently on the 2nd Analog watch ( in the upper right corner of the watch ).

The hands of the Second Analog Watch now take over the role of the Digital Seconds Display. Although if you look closely, the analog and digital seconds indicators are showing different times for now – see picture below …

In my case, the Analog second hand shows 22 seconds and the Digital second hand now shows 07 seconds. Why is this happening ? and how to deal with it ? We’ll take care of it in a moment ! Ok, let’s move on …

From now the Digits Indicating The Seconds ( i.e. in the digital part – LCD display ) will start to blink ! – see picture below …

Another 10 seconds elapsed on my watch, now they show 17 seconds (on the LCD display) – they also flash – see picture below …

3. Resetting The Seconds to Zero ( on the LCD display )

At this point, if you want, you can Reset The Seconds – by comparing the readings on the watch with the time from your computer or another watch.

I, however, adjust my watches according to International Atomic Time * This is Highly Precise Time Scale that is Calculated using data from about 400 Atomic Clocks housed in 69 laboratories around the world. The Time it takes a Cesium-133 atom at the ground state to oscillates exactly 9,192,631,770 times per second !!! This accuracy should satisfy us…

The seconds in our Watch are reset to zero “00” with push of “R” button.

* Typically, ordinary wristwatches are rarely synchronized with the ( Global Atomic Clock ) to an accuracy of one single second. However, if you want to be super accurate – or you want to check if your watch is slowing down or runs too fast – then I recommend you to do this Reset !!!

The procedure for exactly what to do when your watch is running fast or slow is described in the Adjusting Time section.

The Analog watch A2 is also corrected synchronousyly witch the Digital watch ( because both watches are controlled by the same Microprocessor ). Although Seconds are counted Simultaneously on a Digital and Analog watch – as you already know, they can show different times!!! Everything is fine. We will correct The 2nd Analog watch later …

And after my adjustment, the  “hour : minutes” section displays 5:51 .

6. To finish setting the digital time watch, press again the “S” button – then go on to set the mode 12/24 hour format.

12 H display mode

and 24 H display mode – switch by pushing button “R” , as pictured below….

7. How to set 1st analog watch ?

* Note … Is easy to overlook this moment !!!

Now when you press “S” button – hours and minutes – LCD Display – will blink ( just like on my watch – picture below ), this means that we can set 1st analog watch – A1 ( the picture above ) !!!

Push “R” button to precise correction 1st analog watch. One touch “R” button – moves only one step the minute and hour tips !

Also a quick correction ( of 64 Hz ) is possible witch push of “R” button for 1 second or longer.

* You should adjust the Hour and Minutes on 1st Analog watch ( upper left corner of the watch ) – the same as they are now displayed on the Digital watch ( LCD display in the bottom left corner of the watch ) … similar to the picture below – more details.

8. Setting of 2nd analog watch and Synchronizing

Finally we have almost everything set up, but we need to set 2nd analog watch – A2 and Synchronize the Analog and Digitaldisplay …

Do you remember…in my case the difference between digital watch and 2nd analog watch was 15 seconds !

By pushing “S” button we get into the Synchronization.

Note that at this point – display showing seconds ( bottom right corner of the watch ) began to blink, in addition it reset – showing the “00” – see picture below.

* I need to add that this reset is seeming “virtual” , does not apply to Real-Time.

Time and second runs at their own speed ( inside the watch processor ), this evidence is that 1st Analog watch ( upper left corner ) still shows Real Time ( hour & minutes ), in my case 4 : 25 pm / 16 : 25 – see below.

Although the Digital watch displays zero seconds, the real seconds reset ( for example, comparing with the other clock / smartphone ) we did at the beginning of setting time !

The digital watch has just been “virtual” reset.

This is The First Step to Synchronization Digital Watch and 2nd Analog Watch ( A2 ) !!!

Now we also have to “virtual” reset the 2nd analog watch ( That the watch tip would show Zero and more accurately it was at 12/24 o’clock ). And so that later,  the Digital and Analog watch would show the same seconds.

Digital watch is blinking, shows still “00” is a kind of frozen 🙂 … picture below.

Now Push “R” button to precise set 2nd analog watch at the 12-o’clock position (00 – i.e. Reset).

As previously – one touch “R” button – moves only one step, the second hand !

* A quick corretion of 8Hz is also possible witch push of “R” button for 1 second or longer.

I already have set it – the watch tip of 2nd Analog watch ( upper right corner ) is at 12 o’clock. In other words, it shows the same as a Digital watch ( bottom right corner ) that is – Zero ” 00 “ – see picture below …

9. To complete the setting time – press “S” button.

And finished… 🙂

* Note that thanks to this procedure, only now – after pressing the “S” button – will the two Watches start displaying the current (correct) seconds. Analog watch hands will quickly catch up with the virtual reset – and find the right time … From then on, both the digital watch and the analog watch will show the same time ! The right time! Now the analog and digital watches are synchronized. Look…both of them are now simultaneously showing 41 seconds …

And now both clocks show a … 45 seconds …

… 56 second?

Which means that everything is ok 🙂

I hope we helped a little.
