Introducing the Citizen " C Mark Center Seconds" in the 1950s .

 Center seconds refers to a watch with the second hand in the center.

Although this is a common specification today, small seconds with the second hand at 6 o'clock were the mainstream until the 1940s .

Given the technology available at the time, it was technically difficult to create a center seconds dial, and it would also increase the thickness of the watch, so there are many watches with a small seconds dial.

Later, in the late 1940s , watch technology improved further, and overseas-made watches with center seconds began to be introduced.

Therefore, in order to prove its own technology, Citizen released its first watch with a center seconds specification around 1948 .
We have succeeded in promoting the high level of technical capabilities of domestically produced watches to the world.


As the name suggests, the " C Mark Center Second" we are introducing this time is a center seconds model with the second hand attached to the center.

The round case, indexes and hands are also all silver.
The silver color looks great against the black dial, giving it a simple and sophisticated design.

In addition, the indexes are multi-faceted to improve visibility and practicality has been taken into consideration.

In addition, there is an upright index with a C mark at the 12 o'clock position, and at the opposite 6 o'clock position, there are the words " PARA SHOCK ", an earthquake-resistant shock device, which was the most advanced technology at the time, and " PHYNOX ", a mainspring that does not break easily. " CENTER-SECOND " is engraved on the back cover.

This is a watch that skillfully showcases Citizen's technical capabilities and design at the time.

The movement is equipped with a hand-wound Cal.3ADJ using 17 jewels.

This movement incorporates the most advanced technologies of the time, including the center seconds system, Parashock, and Finox.

It is manufactured to a high level in all aspects, including accuracy, practicality, and durability.


Size: Height: 38.8mm , Width: 35.2mm , Thickness: 9.8mm , Weight: 23g .

The simple design allows you to enjoy various expressions depending on the belt, and it can be incorporated into a wide range of outfits from formal to casual.


Regarding the condition, the case has some small scratches due to use, but there are no noticeable scratches and the edges are still intact.

The dial has some scratches due to age, but there are no problems with visibility.

The movement is in good condition.
