Similar Caliber:

There is a similar ETA caliber 980.163, with the main difference between these two is the distance of the small seconds hand from the center of the dial. The difference in distance is:

• 980.153 – 4.25mm
• 980.163 –  6.25mm

All other dimensions are the same.

This difference in distance of the small seconds subdial can allow for a longer case design (lug-to-lug).

Another difference is that the 980.153 has 11 jewels and the 980.163 has 15 jewels. The extra jewels are related to the gear train which moves the seconds hand further away from the center on the 980.163.
