Help wanted.

Hello everyone!

Here it is my first vintage Citizen electro-mechanical watch.
It is made in February, 1971.
This X8 Cosmotron model runs by the caliber 4840 with date function.
This movement has 12 jewels and the frequency is 21.600 bph. Battery type:SR43.

The watch has a nice polished stainless steel case. Case size: 35x41 mm without crown. The caseback is screw type. Case number: 4-480121 Y
The crown is signed "CTZ". Glass is acryl glass with steel ring inside.
Dial is in shinny silver with black signs and blue colored Cosmotron logo.
(dial signs:JAPAN 6-480292 KA)
I installed a black colored 18 mm width leather strap.

Hi.

Today I bought almost the same watch, the only diference it's mine doesnt have the word citizen in the dial, instead of, it have the word Commando , the crown is signed as ctz, also the back and the machine is signed as citizen.

Some one can help me to define if it's a "special model" a replica or what?

thanks a lot
