Following up on my earlier thread, here's a one second exposure

Upon close inspection, I am confident this is a redial. See how the concentric circles in the sunken subdials are not fully defined ?

Now, I also have a similar watch from the 1940s, a Lusserna (Macy's) chronograph, which is a three register

There are some differences in the case designs -- new watch on top

What's inside?

Essentially, you are looking at a calibre 320 on the left and calibre 321 on the right

I love close ups of the calibre 320
